摘要
响应面方法作为一种代替复杂敏度分析的方法在结构优化中取得了很好应用．但是其计算量随设计变量个数的增加而快速增大,为了减少结构分析的计算量,提出了一种采用基函数近似结构总位移的理论,结合响应面方法,在桁架结构截面优化中取得了良好的效果．
Response surface methodology was in good use as a method of replacing the complex sensitivity analysis in the field of structural optimization. Its time cost increased rapidly with the increase of the number of design variables, for this disadvantage, provided the theory of constructing structural displacement with basis function, combined with response surface methodology, the examples of truss section optimization illustrate the feasibility and efficiency of the theory.
