Structural Stability Analysis of Dump Truck Body Based on ANSYS

Abstract

The force on dump truck body is telatively complicated, and different unloading working conditions will have effects on the body structure of dump truck. This paper made a modal analysis and feature buckling analysis of the body structure of dump truck under the unloading situation, and also made a nonlinear analysis under the certain circumstances. Through the ANSYS analysis, the body vibration frequency and buckling modal shape was calculated and figured out, and the design of dump truck body was optimized in order to make sure that the stiffness and stability meet the needs.
