Abstract :
In allusion to the frame of a certain semi-trailer, through adopting ANSYS software, its stress response, modal response and random vibration response were calculated with FEA method under various load cases. The finite element fatigue analysis was carried out in the form of load spectrum, as well as fatigue life and the stress strain variation laws of the vehicle frame under dynamic loads have been obtained, which provide the valuable reference for the vehicle frame structure improvement and optimization. The analysis method adopted in this paper have significance to shorten product design cycle, save cost of testing and producing, reduce the development cost and guarantee the security, stability and reliability of the product.
