Research on Layout of Weld Lines and Size Optimization for TWB Doors
摘要
Abstract
In traditional design process, people always determine the location of weld lines of TWB parts by their personal experience or by a lot of trial and error design, leading the performance of TWB can not be brought into full play. So, in order to improve the design of TWB parts,a new method for the design of TWB parts was generated and applied to improve the stiffness of the car, lighten the total weight by 12. 5%, which was based on bi — directional evolutionary structural optimization, sensitivity analysis method and size optimization. The proposed method can obtain a good optimization results to improve the projects to a certain extent, it promotes the development of China's automobile industry.关键词
