The use of computer programs to analyze vehicle structures is described and the theoretical basis of the computational methods is outlined. The most important contribution of this text is the method of allowing for the different axes defining thin walled beams meeting at the joints.
The scope of this thesis is to make a structural analysis of the Daily vehicle and learn how to correlate the results with the homologation values in order to know if the vehicle would be ready to pass a homologative test. In order to understand this, first of all a brief description of the whole vehicle and their important points has been done, as well as a complete summary of the commercial vehicle most important regulations. The complete structural analysis has been done with numerical models provide by Iveco company, that allow us to focus the study in the parts that have a biggest interest for our results, in that way several configurations of each test have been designed in order to choose the better one. To perform the analysis the software package of Hyperworks has been used, which allow us to make a complete finite element analysis thanks to the pre-processor software Hypermesh or hypercrash to set the mesh and the initial conditions, the solver Radioss of which a complete and detailed explanation of how it works has been done and finally the post-processor to see the results with hyper view. With this entire package it have been possible to perform the analysis as we wanted, as well as report all the necessary data like accelerations, forces, energy... As for the results it will be possible to see a complete analysis and explanations of the performed test in order to achieve the normative. Also from each test, in order to understand the principal behavior of the most important parts, a detailed analysis with a numerical model has been done, in that way it helps to explain in a better way the results and allow us to make a complete correlation if we have it, with the real model. For some cases, it will be possible to see some modifications in the analysis or components, in order to focus the analysis in a more detailed part. At the end, it will be possible to now the most important normative in relation with the passive safety and the commercial vehicles, as well as to understand the used software and how a numerical analysis is performed to obtain the desiderate results, even more and one of the most important points, learn how each component work inside of the vehicle and for which reason have been thought in this way.
Handbook of Automotive Design Analysis examines promising approaches to automotive design analysis. The discussions are organized based on the major "technological divisions of motor vehicles: the transmission gearbox and drive line; steering and suspension; and the automobile structure. This handbook is comprised of three chapters; the first of which deals with transmission gearboxes and drive lines. This chapter describes manual-shift gearbox design, synchromesh mechanisms, hydrokinetic automatic gearboxes, drive-line main assemblies, and drive-line losses. The next chapter is about vehicle suspensions and optimum handling performance, with emphasis on two categories of handling of vehicles: steady-state turning (or cornering) and the transient state. The behavior of the steering system, ride parameters, and the design and installation of spring elements are discussed. The third and final chapter focuses on the application of structural design analysis to the automotive structure. After explaining the fundamentals of structural theory in car body design, this book presents the analysis of commercial vehicle body and chassis. Throughout the book, maximum use is made of line-drawings and concise textural presentation to provide the working designer with an easy assimilable account of automotive design analysis. This book will be useful to young automotive engineers and newcomers in automotive design.
Truck chassis forms the structural backbone of a commercial vehicle. The main function of the truck chassis is to support the components and load that mounted on it. The chassis is experienced a stress whether when it is moving or in a static condition. This paper presents an analysis of the static stress that acting on the upper surface of the truck chassis. These projects study the distributions of the stress that acting on the chassis. Critical parts that will lead to failure are also observed. The method used in this numerical analysis is finite element analysis (FEA). Finite element analysis helps in accelerating design and development process by minimizing number of physical tests, thereby reducing the cost and time for analysis. The commercial finite element package Algor was used for this simulation. 3-D model of the truck chassis was draw by using SolidWorks before analyzed into the simulation software. Numerical results showed that critical part was at the mounting bracket of the tire and also at the front part of the chassis. Some modifications are also suggested to reduce the stress and to improve the strength of the truck chassis.
Thin walled beams warp under torsional and longitudinal loads. Warping restraint produces high longitudinal stresses. This is an analysis of the stress distribution in the side members of commercial vehicle chassis frames under the effects of the previously little studied longitudinal loads which may act on a truck chassis through spring hanger brackets. The structure analysed is a model chassis frame consisting of channel section side members and four cross members with different joint connections. The developed theories are incorporated into a special purpose finite element program which may be used in the preliminary stages of chassis frame design. Although the program is only used for the longitudinal load case in this thesis, it is generally applicable for other chassis load cases, including torsion, bending, . . etc and combination of these. The theoretical results obtained from the program and the finite element analysis on complete chassis frame models are validated against experiments performed on a strain-gauged chassis frame model constructed with the same dimensions and constructional details as the finite element models with the appropriate loading and boundary conditions. Suggestions for the optimum design and attachment positions for components such as spring hanger bracket which may apply longitudinal loads to the side members of the chassis frame are discussed from the point of view of longitudinal loadings.

Dennis Eagle Ltd is a manufacturer of refuse collection vehicles. The company supplies chassis truck cabs to Western Star Trucks (Australia). The service of commercial Western Star vehicles has exposed a problem occurring in some parts of the refuse truck cab. It has been identified by Western Star clients that local failure tends to appear in fillet radii region in the front thin walled sheet metal member. Dennis Eagle Ltd has been requested to investigate the problem and find suitable solution. In the thesis, a thorough strength analysis of the existing cab construction is to be performed based on the loading cases that essentially determine the mechanical response of the truck cab. The cab%s floor structure analysis should be performed as linear static using a Finite Element Method based computer program. From the identified areas of potential local failure a suitable reinforcement for the cab construction is to be found in order to avoid the problem.
