Stiffness Analysis of Light Trucks Frame Based on the FEA

Haishuo Wang

Abstract

CAE model was utilized to calculate bending stiffness and torsion stiffness and validate torsion stiffness by the FEA.Bending stiffness was calculated by 4 locations constrained.Torsion stiffness was calculated by Rear wheels and front-right wheel constrained and front-left wheel forced.Torsion stiffness of the front,middle and rear frame were calculated and validated.
