Abstract The body-in-white finite element model of a type of domestic car was established.The effectiveness and the reliability of the numerical simulation model were verified by comparing the results of prototype vehicle's stiffness,modal test and finite element analysis.On this basis,considered the static and dynamic mechanical property of the body comprehensively,combined lightweight research with manufacture,mass distribution of the thicknesses of body parts was optimized,and dynamic mechanical property was essentially kept.The total mass of the optimized body reduced by 7.84%,the torsional stiffness increased by 1.54% and the bending rigidity increased by 30%. A practical analyzing method of optimizing body structure was provided.
