Abrtrlct The purpose of this study is to examine changes to size and weight limits in order to determine their effects on the designs and configurations of heavy vehicles, the performance capabilities of the resulting vehicles, and the ensuing safety implications thereof, The summary report provides results and findings fiom an analytical investigation of the influences of size and weight limits on trucks. In an analytical sense, pavement loading rules and bridge formulas are the inputs to the analyses and vehicle performances are the outputs. Ultimately, the work shows the manner in which size and weight rules influence the safety-related performance of vehicles designed to increase productivity. By treating a number of projected size and weight scenarios, the study has developed a basis for generalizing to sets of principles that can be used in evaluating the possible safety consequences of changes in size and weight regulations.

  • Parameter Sensitivity of the Dynamic Roll Over Threshold
    7th International Svmposium on Heavv Vehicle Weights & Dimensions Delft. The Netherlands• .June 16 - 20. 2002 PARAMETER SENSITIVITY OF THE DYNAMIC ROLLOVER THRESHOLD Erik Dahlberg Scania cv AB, SE - 151 87 Sodertalje, Sweden ABSTRACT Knowledge of commercial vehicle rollover mechanics, required in the development of active dynamic control systems and when designing for increased safety, commonly relies on static analysis providing the steady state rollover threshold, SSRT. In a rolling vehicle kinetic energy is always present and that deteriorates the analysis of roll stability from SSRT. Therefore, knowledge of the dynamic rollover threshold, DRT, is equally relevant. In order to investigate the parameter sensitivity of the dynamic rollover threshold, the Taguchi method is applied: simulations are performed according to a specific plan forming an orthogonal matrix existing of high, medium and low parameter values. The influences from five test parameters on SSRT as well as DRT of a truck and a tractor semitrailer combination are calculated, including the corresponding parameter interaction effects. Investigated parameters are frame roll stiffness plus axle roll stiffnesses and roll center heights offront and rear axles. Results show that the different vehicles are unequally sensitive to parameter changes: the rear axle roll characteristics are the most important semi trailer parameters, while the front axle roll stiffness is most important for the truck. An important result yielding from this is that two vehicles can be equally stable statically but different dynamical!.\'. INTRODUCTION Commercial vehicle roll over has grave implications: the accident type contributes substantially to injuries but also to environmental damage. Several vehicle occupants are seriously injured or killed every year and vehicles carrying hazardous goods often waste it.

  • Truck Size and Weight Study Phase I: Working Papers 1 and 2 Combined
    Truck Size and Weight Study Phase I: Working Papers 1 and 2 combined Vehicle Characteristics Affecting Safety Paul S. Fancher Kenneth L. Campbell University of Michigan Transportation Research Institute This paper addresses the relationship of truck size and weight (TS&W) policy, vehicle handling and stability, and safety. Handling and stability are the primary mechanisms relating vehicle characteristics and safety. Vehicle characteristics may also affect safety by mechanisms other than handling and stability. For example, vehicle length may affect safety through interactions with other vehicles, such as passing maneuvers and in clearing intersections, in addition to its influence on vehicle handling and stability. However, the safety effect of vehicle length due to its influence on handling and stability is within the scope of this paper, while safety effects arising through mechanisms other than handling and stability, such as passing and intersection clearance, are not. There is no direct relationship between TS&W policy and safety. Vehicle characteristics are altered in response to TS&W policy, and vehicle characteristics also influence handling and stability. A wide variety of vehicle characteristics may satisfy a given TS&W policy, and a wide range of safety effects can result. This paper begins with a discussion of the recent history of TS&W policy, and the influence of past policy on safety. The technical relationships between vehicle characteristics and safety are summarized in Section 2. This material has been condensed from a rather large body of literature. Performance measures are introduced to describe (quantify) the capability of the vehicle in various maneuvers. The material in Section 2 summarizes the relationship of various vehicle characteristics and pertinent performance measures (roll threshold, rearward amplification, braking efficiency, and offtracking).

  • Analytic Determination and Numerical Simulation of Torsional Stiffness of a Racing Car Frame
    28TH DAAAM INTERNATIONAL SYMPOSIUM ON INTELLIGENT MANUFACTURING AND AUTOMATION DOI: 10.2507/28th.daaam.proceedings.094 ANALYTIC DETERMINATION AND NUMERICAL SIMULATION OF TORSIONAL STIFFNESS OF A RACING CAR FRAME Michal Skovajsa, Frantisek Sedlacek This Publication has to be referred as: Skovajsa, M[ichal] & Sedlacek, F[rantisek] (2017). Analytic Determination and Numerical Simulation of Torsional Stiffness of a Racing Car Frame, Proceedings of the 28th DAAAM International Symposium, pp.0671-0678, B. Katalinic (Ed.), Published by DAAAM International, ISBN 978-3-902734-11-2, ISSN 1726-9679, Vienna, Austria DOI: 10.2507/28th.daaam.proceedings.094 Abstract The paper deals with the determination of the required torsional stiffness of the frame of a racing car. The required torsional stiffness of the frame was performed by analytic computation. The analytic computation deals with the transfer of the vertical load of the tyre between the front and rear axle for different roll stiffnesses of axles and torsional stiffnesses of the frame. The analytic computation determines the ratio between the roll stiffness of the axles and the torsional stiffness of frame. NX Nastran 11 software was used for the numerical simulation. The numerical simulation was performed by using four different numerical methods. Each numerical simulation was performed with different boundary conditions. Keywords: Torsional stiffness; frame; numerical simulation; analytic solution 1. Introduction Determining the correct ratio between the roll stiffness of the car and the torsion stiffness of the frame is covered by several publications. [1, 2, 3]. The numerical simulation of the torsion stiffness of the frame is covered by some publications [5,6].
