Abstract

Aiming at the problems of long test cycle, high cost and unable to evaluate the development scheme of vehicle in the early stage, the durability solution based on virtual proving ground has been widely used in vehicle development. In this paper, the fatigue analysis of truck frame is proposed based on VPG. Three key technologies, high precision laser scanning of pave, tire parameter identification and full vehicle modeling are discussed. The dynamic model of a truck with flexible frame is established. Based on the durability test criterion of the proving ground, the dynamic load decomposition of the frame is completed, and then the fatigue life evaluation of the frame is carried out, which verifies the feasibility of this new technical scheme.
