Abstract

The invention provides an optimization method for an automobile body material. The optimization method for the automobile body material comprises the steps of obtaining material performance evaluation index and part performance evaluation index, and pre-defining a rank division range of the material performance evaluation index and the part performance evaluation index; establishing an initial information sheet of to-be-optimized parts according to design parameters and a material list of the to-be-optimized parts, wherein the initial information sheet comprises part names and material names; obtaining a grading result corresponding to the material performance evaluation index and the part performance evaluation index according to the part names and the material names in the initial information sheet; and comparing the material performance evaluation index and the part performance evaluation index according to an optimization target under the premise of not influencing design performance of the parts so as to obtain an optimization scheme with better material performance evaluation index and the part performance evaluation index. The invention also provides a selection and evaluation apparatus for the automobile body material, wherein the selection and evaluation apparatus comprises a pre-defining module, an initial information establishing module, a rank grading module and a screening module.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an optimization method and an optimization system for automobile body materials. Background technique [0002] With the improvement of people's living standards and the rapid development of the automobile industry, more and more cars are used in people's daily life. In the continuous development of the automobile industry, people pay more and more attention to the safety of the automobile body besides the quality and function of the automobile. [0003] Automobile bodies usually use bake-hardening (BH) steel plates, interstitial-free steel (Interstitial-Free Steel, IF steel) plates, low-alloy high-strength steel plates, dual-phase steel plates, phase transformation-induced plasticity (TRIP) steel plates, hot-formed high-strength Steel plates, and vibration-damping composite steel plates, etc., which can increase the structural strength and rigidity of the vehicle body, reduce the weig...
