Fatigue analysis of electrical vehicle chassis

Abstract

The aim of this study is to make fatigue analysis of electrical vehicle chassis which was designed previously and is to determine the fatigue damage components in advance and to find the critical life of these parts. Then to compare the obtained data with the values taken during the road tests.To ensure smooth operation CAD model which was prepared in Solidworks is provided in .stp format and simplifications that are deemed necessary are made in the program Catia V5 R20.The prepared solid model has been transferred to the Ansys Static Structural Programmer in .stp format for finite element models. Here, static analysis is performed via on-vehicle weight. After that, fatigue analysis is performed in nCode DesignLife software with the data received from testing tracks. Within the scope of this plan, firstly static analysis will be performed with 1 driver and 2 passenger weights on the chassis, than fatigue analysis with data collected from 4 different ways during road tests will be carried out..And finally, according to the analysis results fatigue life of the parts on the model will be examined.
