基于灵敏度分析的串杆结构优化设计

在串杆的结构设计中引入灵敏度分析理论，通过对串杆相关结构参数相对于串杆重量以及串杆危险截面应力的灵敏度分析，确定各设计参数对重量变化和对应力变化影响程度。并根据灵敏度分析结果，确定最适合的优化方案，从而得到串杆的最优结构尺寸。该设计思路更加适合参数较多的复杂结构件的优化设计，可以为优化参数的设置提供科学的指导。

Optimal design of string rod structure based on sensitivity analysis

Introduce sensitivity analysis theory into structure design of string rod,through sensitivity analysis for related structure parameter of string rod relative to string rod weight and dangerous cross section stress of string rod,determine eaoh design parameter effect for weight change and stress change.Determine the most suitable optimization scheme according to sensitivity result, in ordet to obtain optimal structure dimension.This design idea is more suitable for the optimal design of complicated structure parts with more parameters,which can provide scientific guidance for the setting of optimization parameter.
