Fatigue Calculation of a Car Component Subjected to Random Vibrations

In this article, a random vibration simulation approach applied to a car component is presented. The main vibration sources which appear in the automotive body are mentioned as input for random analysis. By using finite element analysis, one can estimate the response of the structure in terms of the probability of the maximum displacement and stress. The normal distribution function was used in the analysis for the statistical interpretation of the results. By using the random vibration simulation method, the response of a structure excited by random vibrations can be estimated, with a good precision for various applications. The resulted stress it is used to perform fatigue evaluation by using Palmgren Miner method.
