零件设计过程多学科协同优化
Multidisciplinary collaborative optimization for parts design process
摘要
Abstract
Based on the fact that sequential process of parts design and optimization cannot achieve the global optimization for the load-structure-process, the process of shaft multidisciplinary design optimization was built. Taking quality as the system-level objective function, and taking the bending moment and concentrated load torque, the changed safety foctors and the total amount of material removal machining as the disciplines objective function in cross-section, genetic-particle swarm algorithm method was built, and the optimization calculation of EPS output shaft was made. The results show that the output mass is reduced by 5.5%, and at electric power-assisted moment of 300 Nm and 80 N穖, the maximum deformations reduce by 4.2% and 9.6%, and the maximum stresses decrease by 4.4% and 10.1 %, respectively.关键词
