摘要
以二维单元为例，推导给出线性静力结构优化设计中解析灵敏度算法的计算公式，以有限元分析程序ＡＤＩＮＡ为基础实现了解析灵敏度算法的计算功能，并通过算例验证了其精度。
As an example,formulae for analytical sensitivity of structure response of a two dimensional element in linear static structure optimization design are given.Analytical sensitivity algorithm and its calculating function are also developed by means of ADINA.Results of computational examples verify the accuracy of analytical sensitivity algorithm.
