摘要
该文采用基于变形修正的模型简化方法对原始复杂结构模型进行简化,在此基础上建立了基于变量分离技术的最大化结构基频为目标的优化模型。该文通过具体算例实现这一方法并验证其有效性,并且和基于响应曲面法的优化方法比较,分析了两种方法的优缺点。
In this paper,a reduced model of a complex structure is obtained though a model reduction method based on deformation modification,then an optimization model based on variable decomposition is established,in which the structural fundamental frequency is maximized.The examples show the validity of this method.The method is compared with the response surface method-based structural optimization approach.The advantage and disadvantage differences of these two models are analyzed briefly.
