(continued on back cover) and Technology REPORT S U M M AIRY EPRI Leadership inScience Bolted Joint Maintenance &Applications Guide This guide consolidates key information previously published by NMAC. The primary focus is on the design and assembly of pressure boundary, mechanical, and structural bolted joints. This document helps plant engineering and maintenance personnel with the assem bly and inspection of various types of bolted connections used in nuclear power plant applications. BACKGROUND In the past 20 years, the NRC has issued numerous docu ments highlighting concerns with the integrity of bolted connections including pressure boundary, mechanical, and structural joints. The commercial nuclear power industry has responded with initiatives to resolve the issues. Numerous Electric Power Research Institute (EPRI) and Nuclear Maintenance Applications Center (NMAC) publications were recognized by NUREG-1399 as contributing INTEREST CATEGORIES to the resolution of concerns. Significantly, the NRC emphasized the usefulness of utility plant-specific programs and the need to continue to address the issues Maintenance practices identified in previous NRC guidance. Nuclear plant operations and maintenance OBJECTIVES Engineering and technical - To update, augment, and consolidate previously published NMAC information support • To provide additional technical information to allow seamless integration of the material into a single document KEYWORDS with information obtained from Design APPROACH This document contains tables various referenced sources. The objective was to consolidate and reproduce Assembly information as a handy reference. Information on design and assembly includes Bolted connections guidance and illustrations that convey key concepts and critical success factors. Threaded fasteners Effort has been made to illustrate the relationship between the design and assembly processes. RESULTS This document is divided in parts or topical sections for pressure retaining joints, mechanical joints, structural joints, and threaded fasteners. Chapters in each part cover design considerations, assembly, inspection, and troubleshooting and repair. The section on threaded fasteners addresses selection, specification and procurement, and receipt inspection. EPRI PERSPECTIVE Proper design, assembly, preload, and inspection of bolted connections remains an important activity for operators of commercial nuclear power plants. Likewise, plant leakage reduction efforts continue to receive attention at most of these generating facilities. NMAC's Bolted Joint Maintenance & Applications Guide addresses these areas of interest and represents both a major revision and a consolidation of several previous guide books dealing with general good bolting practices and guidelines for the use of threaded fasteners.

  • Threaded Fasteners
    Threaded Fasteners Introduction If you are designing and building a Formula SAE vehicle, threaded fasteners will likely be used to join the various components and systems together and allow the vehicle to function as a unified machine. The reliability of your vehicle is key to realize your potential at the competition. Even though threaded fasteners have been in use for hundreds of years and are in products that we use every day, their performance is dependent on a wide range of factors. This chapter covers some of the main factors that can influence reliability and is intended as an aid in joint design, fastener selection, and installation. The first portion of this chapter covers several design and installation factors that can work together to improve the reliability of your vehicle’s bolted joints. These topics include, the importance of generating and maintaining clamp load, and how clamp load, along with joint stiffness, can work together to prevent self-loosening and improve fatigue performance. The second portion of this chapter reviews how installation method and torque are related to clamp load, and also includes a comparison between common fastener types to aid in selection. The chapter concludes with a short tutorial showing how to obtain Mil Spec information on fasteners and similar hardware. Disclaimer – Multiple factors on each component in a bolted joint affect its performance. Additionally, service requirements for every joint differ. Each joint must be evaluated and tested for its ability to perform the desired function. The information in this chapter provides general background and does not represent how a specific design or piece of hardware will perform.

  • Bolted Timber Joints with Self-Tapping Screws
    Revista EIA, ISSN 1794-1237 Número 8, p. 37-47. Diciembre 2007 Escuela de Ingeniería de Antioquia, Medellín (Colombia) BOLTED TIMBER JOINTS WITH SELF-TAPPING SCREWS CÉSAR ECHAVARRÍA* ABSTRACT The use of self-tapping screws with continuous threads in the joint area as a reinforcement to avoid splitting of timber members is studied. A theoretical model is developed to calculate the stress distribution around a pin-loaded hole in a timber joint, to predict brittle failure modes in bolted connections and to cal- culate the load in the reinforcing screws. Laboratory experiments on reinforced and non-reinforced timber joints with 15,9-mm bolts have shown good agreement with the model predictions. KEYWORDS: timber joints; brittle failure mode; reinforcement perpendicular-to-grain; analytical model. RESUMEN En este artículo se estudia el uso de tornillos autoperforantes como refuerzo para evitar rupturas frágiles en uniones de madera. Se presenta un modelo teórico para calcular la distribución de esfuerzos alrededor de un perno en una unión de madera, predecir las rupturas frágiles y evaluar el esfuerzo en los tornillos autoperforantes. Los ������������������������������������������������������������������������experimentos de laboratorio con uniones de madera, con pernos de 15,9 mm de diámetro, reforzadas y no reforzadas mostraron la efectividad del modelo teórico propuesto.

  • Bolted Joint Design
    Bolted Joint Design There is no one fastener material that is right for every environment. Selecting the right fastener material from the vast array of those available can be a daunting task. Careful consideration must be given to strength, temperature, corrosion, vibration, fatigue, and many other variables. However, with some basic knowledge and understanding, a well thought out evaluation can be made. Mechanical Properties of Steel Fasteners in Service Most fastener applications are designed to support or transmit some form of externally applied load. If the strength of the fastener is the only concern, there is usually no need to look beyond carbon steel. Considering the cost of raw materials, non-ferrous metals should be considered only when a special application is required. Tensile strength is the mechanical property most widely associated with standard threaded fasteners. Tensile strength is the maximum tension-applied load the fastener can support prior to fracture. The tensile load a fastener can withstand is determined by the formula P = St x As . • P= Tensile load– a direct measurement of clamp load (lbs., N) • St= Tensile strength– a generic measurement of the material’s strength (psi, MPa). • As= Tensile stress area for fastener or area of material (in 2, mm 2) To find the tensile strength of a particular P = St x As bolt, you will need to refer to Mechanical P = tensile load St = tensile strength As = tensile stress area Properties of Externally Threaded Fasteners (lbs., N) (psi, MPa) (sq. in, sq. mm) chart in the Fastenal Technical Reference Applied to a 3/4-10 x 7” SAE J429 Grade 5 HCS Guide.

  • Joints and Structural Members
    TITLE 5. JOINTS AND STRUCTURAL MEMBERS CHAPTER XIV. JOINTS Section 55. General 55.1. Bases Joint connections in a structure should be designed to fulfil the intended level of safety, serviceability and durability, and the ability to withstand at least the stresses provided for them in the global analysis of the structure. 55.2. Manufacture and assembly Joints should be designed for ease of use and safety. Special attention shall be paid to providing the space required to: Assemble components safely. Tighten the bolts. Need for access for welders. Accessibility for people in charge of performing protection and maintenance treatments and inspection work, and their teams. The effect of the length and angle tolerances between the faces of a single part on the fit with contiguous parts should also be taken into account. 55.3. Transmission of forces The arrangement of each joint shall be studied to ensure that, with a minimum of members, the existing forces are transmitted under the best possible conditions and so as to minimise secondary forces. 55.4. Nodes in triangular structures In the case of triangular structures, compliance with the above condition shall be facilitated if the axes of the bars to be joined in a node come together in a point and when the angle formed by contiguous bars is between 30º and 150º. If both conditions are met, it may be assumed that the bars are joined in the node. This assumption may not be made if the second condition is not met, or if any loads are applied to intermediate points of the bar other than its own weight or the direct action of the wind, or if the ratio of span to height of the structure is less than 6.

  • Bolted Joint Analysis
    EXPERIMENTAL AND FINITE ELEMENT ANALYSIS OF A SIMPLIFIED AIRCRAFT WHEEL BOLTED JOINT MODEL A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Masters of Mechanical Engineering in the Graduate School of The Ohio State University By Kathryn J. Belisle ***** The Ohio State University 2009 Thesis Defense Committee: Approved by Dr. Anthony Luscher, Adviser _____________________________ Dr. Mark Walter Adviser Graduate Program in Mechanical Engineering Copyright © by Kathryn J. Belisle 2009 ABSTRACT The goal of this thesis is to establish a correlation between experimental and finite element strains in key areas of an aircraft wheel bolted joint. The critical location in fatigue is the rounded interface between the bolt-hole and mating face of the joint, called the mating face radius. A previous study considered this area of a bolted joint but only under the influence of bolt preload. The study presented here considered both preload and an external bending moment. This study used a more complete single bolted joint model incorporating the wheel rim flange and the two main loads seen at the bolted joints; bolt preload and the external load created by tire pressure on the wheel rim. A 2x3 full factorial DOE was used to establish the joint’s response to various potential load combinations assuming two levels of preload and three levels of external load. The model was analyzed both experimentally and in finite element form. The strain results around the mating face radius were compared between the two analyses. Several parameters were identified that could affect the correlation between the results. The finite element model was modified to incorporate each of these factors and the new results were compared against the original finite element results and the experimental data.

  • Optimal Tightening Process of Bolted Joints
    Int. J. Simul. Multisci. Des. Optim. 2016, 7,A4 Ó J.-M. Monville, Published by EDP Sciences, 2016 DOI: 10.1051/smdo/2016005 Available online at: www.ijsmdo.org REVIEW OPEN ACCESS Optimal tightening process of bolted joints Jean-Michel Monville* MZ Intelligent Systems, 21 Boulevard de Lozère, 91120 Palaiseau, France Received 28 April 2016 / Accepted 17 June 2016 Abstract – Threaded fasteners were developed long time (let’s remember that Archimedes – 287-212 BC – invented the water screw). Nowadays, bolted joints are used in almost all sectors of the industry. But in spite of having been an important machine part for centuries, problems may be encountered with them. They are so common that they are taken for granted and too often, not analyzed as deeply as it should be. The wrong tightening is one of the most frequent causes of ductile rupture and by far the most frequent cause of fatigue failure. The tightening operation is never easy. It is necessary to pay particular attention to the choice of the tightening tool, the process and the control method. The tightening operation may itself cause damage on parts. The tightening load must not be too low, or excessive or not equally distributed among the bolts. These three defects can even be made on the same bolted joint! This impacts badly the performance of the assembly and leads to a shorter lifespan. If insufficient precautions are taken, the real tightening preload on all the bolts will not fit well with the requirements and would be badly distributed. Consequently, the practical conditions are quite different from the hypothesizes which are taken for the initial calculations (analytics or FEM) at the design stage.

An important factor in this are the components ability to withstand fatigue and to provide designs to improve fatigue strength limit. A design element that occurs in many components construction is the bolted joint, particularly for circular casings. The conditions for these are also susceptible to fatigue failure. This report focusses of the surface flatness of bolted joints used in flanges and with the help of CAE-programs find the best way of modeling the specific problem. The threads in the bolt and nut are complicated to model accurately. Therefore, some alternative solutions were evaluated and verified as acceptable. When a proper way to model the thread was found, this study was focused on investigate the influence of a deviating surfaces on flanges where bolted joints are applied.
