摘要:
通过电磁推动装置移动大负载的近似模拟及优化参数设置,进行了该装置的结构拓扑优化概念设计。通过Abaqus中的VDLOAD子程序二次开发解决移动变化大负载的有限元动态加载问题。基于刚度均衡性设计方法、包含全部关键形状及尺寸设计变量的全局优化方法,并且通过人工调整,采用实数编码的遗传算法对推动装置结构性能进行优化。结果表明,在满足推力稳定性的前提下,该文方法解决了电磁推动装置结构的大负载高刚度问题,且系统整体刚度在控制范围内,实现了高刚度与轻量化的平衡。
Abstract:
The topology optimization concept design of the structure is completed by the approximate simulation and optimizing parameter setting of an electromagnetic-propelling device with a moving large load. The dynamic loading problem of moving large load infinite element analysis is solved by the VDLOAD subprogram second development of Abaqus. The final structure performance of the electromagnetic-propelling device is optimized by the real-code genetic algorithm based on the stiffness equilibrium design method,the global optimization method including all key shapes and design variables and manual adjustments. The results show that the electromagnetic-propelling device meets its large load and high stiffness,the requirements of thrust stability and the equilibrium of the structural stiffness and light weight; the overall stiffness of the system is controlled within a certain limit.
