复杂结构系统失效模式的响应面法

RESPONSE SURFACE METHOD FOR THE FAILURE MODELS IN A LARGE COMPLEX STRUCTURAL SYSTEMS

讨论了响应面方法的发展现状 ,根据大型复杂结构系统具有变量多和非线性程度高的特点 ,指出这将是影响响应面法应用的主要障碍。由此提出相应的改进方法。算例表明 ,该方法在与原方法精度要求相同的前提之下 。

The development of response surface methods (RSM) is reviewed at first. Because there are many variables and hight nonlinearity in a large complex structural system and it is an obstacle to RSM, a improvement method is presented. The illustrative calculation shows that this method has a high efficient calculation than others.
