Abstract：

The lightweight evaluation of heavy truck frames was studied, and a method of evaluating optimal lightweight design of heavy truck framed was put forward. For the optimal lightweight design of a domestic-made heavy truck frame, and the study on strength, rigidity and modal analysis of the improved frames were conducted by finite element method. Meanwhile, the verification is done by a bench test. The results show that both the finite element analysis and the experimental verification are within the allowable error range, which proves the validity of the evaluation method. Therefore, this method provides a basis for heavy truck lightweight evaluation. However, the forming process of the frame is studied in the manufacturing, which optimizes the process and equipment，improves the accuracy of the frame manufacturing, and provides a powerful guarantee for the lightweight.
