Finite Element Analysis of Heavy-Duty Dump Truck Subframe Based on ANSYS

Dump truck subframe is an important bearing components which is used for connecting the chassis frame and the cargo compartment, and the rationality of its design has an extremely important influence on performance of the entire vehicle, moreover, the use of CAE technology can optimize the design of the subframe. In this paper, using solid element as basic element, the finite element analysis model of dump truck frame is built up with the software ANSYS, the static characteristics of the subframe under bending mode, twisting mode, braking mode and lifting mode are studied. The dynamic characteristics of the subframe are also analyzed, the stress parameters under static characteristics, the natural frequency and the corresponding mode shape characteristics of the subframe under dynamic characteristics are obtained, the improved advice of structural design for the subframe is proposed.
