燃料组件修复系统工作平台轻量化设计

摘要

Aiming at lightweight design for the work platform of fuel assembly repair system,this paper optimizes the structural design of the work platform for fuel assembly repair system by applying theories such as single objective flexibility topology optimization,single objective natural frequency topology optimization,and multi-objective topology optimization.The results show that in the case of a certain weight reduction,better dynamic and static performance of the work platform can be obtained by using multi-objective topology optimization.%为满足燃料组件修复系统的工作平台轻量化设计的要求,分别采用单目标柔度拓扑优化理论、单目标固有频率拓扑优化理论、多目标拓扑优化理论,对燃料组件修复系统的工作平台进行结构优化设计.优化结果表明,在重量减少一定的情况下,多目标拓扑优化能够获得动静态特性均优的工作平台.
