Summary:The invention discloses a material-structure-process integrated automobile part lightweight design method which comprises the following steps: (1) establishing a part initial model, and carrying out finite element analysis to obtain various performance parameters; (2) determining a replacement material and a manufacturing process, and performing re-integrated design on the initial model structure based on the material and the process; (3) verifying whether the reconstructed model meets performance requirements or not; (4) carrying out structure topology optimization solution on the reconstructed model; (5) extracting an optimal solution reaching an optimization target, and redesigning the structure; (6) verifying the process feasibility of the optimized model; and (7) comparing the performance parameters before and after optimization to obtain a conclusion. According to the method, the reliability and engineering applicability are high, the coupling effect of multiple factors of light weight is comprehensivel
