The Structure Optimization of Pedestal for Lightweight

摘要: 基座作为机械结构重要承重件，其强度性能直接关系整机安全。针对筋板式基座结构，其构成件厚度是设计的关键点，以改善基座结构强度、降低重量为优化目标，以基座构成件结构参数为优化变量对基座进行结构优化，计算出较优的基座构成件尺寸参数，保证在满足强度要求的前提下，实现基座轻量化设计。

Abstract: As an important load-bearing part of the mechanical structure, the strength of the pedestal is di-rectly related to the safety of the whole machine. For the stiffened base structure, the thickness of the components is the key point of the design for the stiffened pedestal structure. The optimization goal is to improve the structural strength of the pedestal and reduce the weight of the pedestal. Taking structural parameters of the pedestal components as optimization variables, the pedestal structure is optimized and the better parameters of the pedestal components are obtained. The weight of the pedestal is reduced on the premise of meeting the strength requirements.
