ABSTRACT: Heavy duty vehicle plays a more important role in highway transportation. The major focus in the truck manufacturing industries is design of truck chassis with more pay load capacity and possible less weight. An important aspect of chassis’ design and analysis is the stress distribution and fatigue life of prediction process. Fatigue is one of the most important parameters to consider when designing truck components. The components are typically subjected to dynamic loads when in service. In this paper, an effort is made to review the investigations that have been made on the different fatigue analysis techniques of heavy duty truck frames. A number of analytical and numerical techniques are available for the fatigue analysis of the heavy duty truck frames has been reported in literature. KEYWORDS : Heavy duty truck, Chassis frames, Fatigue analysis. I. INTRODUCTION Transportation industry plays a major role in the economy of modern industrialized and developing countries. The early damages caused by heavy load reduce the road service life and ride comfort. Highway maintenance brings huge economic losses, while serious road failure threats traffic safety. Chassis is one of the most significant components in automotive industry and is considered as the bigger parts in the vehicle. The chassis of trucks is tasked with holding all the components systems together; hence it should be rigid enough to withstand the shock, twist, vibration and other stresses. Along with strength, an important consideration in chassis design is to have adequate bending stiffness for better handling characteristics. So, maximum stress, maximum equilateral stress and deflection are important criteria for the design of the chassis. The greater the energy absorbed by the chassis on impact the lower the energy levels transmitted to a vehicles occupants and surroundings, lowering the chances of injury [1]. The chassis of trucks which is the backbone of vehicles that integrates the main truck component systems such as the axles, suspension, power train, cab and trailer etc., is one of the possible candidates for significant weight reduction [2]. In general, the chassis experiences several loading situations that include vertical bending, longitudinal torsion, lateral bending, torsion loading and fatigue loading [3]. In additions, the chassis design includes the selection of suitable shapes and cross-section of chassis-members. Moreover, the design should consider the reinforcement of the chassis side- and cross member joints, and the various methods of fastening them together. There are number of parameters which affect the fatigue life of the structure as listed: cyclic stress state, geometry, surface quality, material type, residual stresses, size and distribution of internal defects, direction of loading & grain size. Many researchers in the automotive industry have taken this opportunity to be involved in the chassis manufacturing technology and development [2].The objective of this review paper is to present the fatigue analysis techniques of heavy duty truck frames. Prevention of fatigue failure is one of the most important parameters to when designing truck components. The components are typically subjected to dynamic loads when in service. A number of analytical, numerical and experimental techniques are considered for the fatigue analysis of the heavy duty truck frames. Conclusion of the fatigue analysis in the vehicle chassis has been reported in literature. www.ajer.org Page 1 American Journal of Engineering Research (AJER) 2014 II. ASPECT OF TRUCK CHASSIS FRAME The common chassis frame consists of two channel shaped side members that are sustained apart by many cross members, as shown in Figure1. The cross members are placed at points of high stress and are joined to side members. The depth of the channel must be enough to reduce the deflection. Since the load at each point of the frame varies, a weight reduction can be achieved by either minimums the depth of the channel, or having a series of holes positioned along the axis in the regions where the load is

    Assistive Multi-Purpose Mobility Device with Folding Temporary Seat A Major Qualifying Project Proposal Submitted to the Faculty of WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science by _________________________ Xinping Deng _________________________ Daniel Haley _________________________ Taylor Roseen Date: 4/30/15 Approved: ______________________________ Professor Allen H. Hoffman, Co-Advisor ______________________________ Professor Holly K. Ault, Co-Advisor Abstract Crutches and canes are widely used around the world as a means of providing stability and support for those who need them; the elderly population in particular utilizes these devices the most. There are numerous products on the market that attempt to add a seat to the crutch or cane in an effort to alleviate the stress of standing for too long. However, these products are oftentimes too cumbersome, heavy, or just simply unsafe. The goal of this project is to design and build a device that can be used as either a crutch or a cane that gives stability and helps support the weight of the user while standing and walking, additionally offering the ability for the user to rest comfortably and safely in a seated position when necessary. A first generation prototype was successfully manufactured using an existing forearm crutch and machined aluminum and steel components. The prototype underwent load and dimension tests in addition to students conducting overall usability tests. i Table of Contents Abstract .........................................................................................................................................................

Thirty-nine million people are estimated to be blind, whereas 246 million people are estimated to have impaired vision. An important factor that motivated this research is the fact that 90% of VI people live in developing countries. Several systems have been designed to improve the quality of the life of VI people and support the mobility of VI people. Unfortunately, none of these systems provides a complete solution for VI people, and the systems are very expensive. Therefore, this work presents an intelligent framework that includes several types of sensors embedded in a wearable device to support the visually impaired (VI) community. The proposed work is based on an integration of sensor-based and computer vision-based techniques in order to introduce an efficient and economical visual device. The designed algorithm is divided to two components: obstacle detection and collision avoidance. The system has been implemented and tested in real-time scenarios. A video dataset of 30 videos and an average of 700 frames per video was fed to the system for the testing purpose.

Abstract This thesis contributes to a growing body of research conducted by the Interactive Systems Research Group (ISRG) at Nottingham Trent University within the fields of accessibility and accessible technologies. Core to this research is the exploration of how interactive technologies can be developed and applied as platforms for education, rehabilitation and social inclusion. To this end the group has been actively evolving the User Sensitive and Inclusive Design (USID) methodology for the design, development and evaluation of accessible software and related technologies. This thesis contributes to the further development of the USID method with a focus on its application for the design of assistive technology. Video Games are increasingly being recognised as an important resource for the development and improvement of the quality of life of those with a disability and/or impairment. Creating universally accessible games and related technologies is however no simple feat. Review of literature quickly highlights that the predominant barrier to the adoption of console gaming and also video gaming in general, by those with a disability or impairment, is that of the human-machine hardware interface.
