Finite Element Analysis and Optimization of Medium Truck Frame Based on ANSYS

Frame is one of the most important parts of a car chassis. As the most basic part of a car, the research of frame plays a very important role in the safety of the vehicle. The research content of this topic is the statics and dynamics of a certain type of truck are analyzed, and CATIA is used for modeling. By building a model of the frame and analyzing it under two working conditions with ANSYS, the stress change diagram of the frame under two different working conditions is obtained. The first 10 free modes of the frame are calculated by modal analysis. The frequency and vibration pattern of the frame in each mode are obtained, and then the possibility of the cab forming resonance with the road surface is analyzed on this basis. On this basis, the size of the frame is optimized, and the easy fracture area is strengthened, and a feasible optimization scheme is proposed.
