结构优化设计中减少调用结构分析次数的方法

A Method for Reducing the Call Number of Structural Analyses in the Structural Optimal Design

本文在研究广义插值方法的基础上,提出了一种在结构优化设计计算中减少调用结构分析次数的方法,并在理论上和计算实践中,证明了该方法的正确性与有效性,从而解决了长期以来困扰深入应用优化方法的一个难题.

Since the program system for structural analysis has to be called again and again in the structural optimal design calculation based on the finite element discretion, extremely high cost has hitherto hindered the wide application of the structural optimal design approach. A method for reducing the call number of structural analyses in the calculation is proposed on the basis of a study of the generalized interpolation. The feasibility of the method has been proved in practice.
