Abstract

The invention discloses a thermoforming part performance reliability design method considering manufacturing factors. The invention belongs to the technical field of hot stamping forming. Hot stampingprocess parameters and hot stamping part structure parameters are comprehensively considered; According to the method, the probability of failure of the thermoformed part is fully considered, and onthe basis of a reliability optimization design method, under the condition that the mechanical property of the part is improved, the rejection rate of the part is greatly reduced, and the design development efficiency and the production efficiency of the part are improved. Meanwhile, the software used in the implementation process of the patent of the invention is universal CAE software, has the technical characteristics of fast calculation process, efficient mapping process, simple data extraction and the like, is easy to popularize and use on a large scale in the design and development of the automobile thermoforming part, and contributes to improving the part design level of the automobile thermoforming part. The design method is simple, practical and easy to implement, and has wide application prospects in the hot stamping forming design and development process of the automobile parts.

Description

technical field [0001] The invention belongs to the technical field of hot stamping, and in particular relates to a method for designing performance reliability of hot formed parts considering manufacturing factors. Background technique [0002] With the rapid development of the automobile industry, automobile safety, energy saving and environmental protection have become important research directions. The design of vehicle structure lightweight and crashworthiness has received extensive attention. But these two goals always conflict with each other. In order to solve this problem, hot-formed ultra-high-strength steel (UHSS) is increasingly used to maintain the crashworthiness of lightweight design products, and scholars have conducted many related studies in this regard. [0003] However, compared with the cold stamping process, the hot stamping process is more complicated, including heating stages, stamping stages and quenching stages. In addition, due to the phase tran...
