摘　　要：结构优化设计中 ,常遇到具有奇异性的结构优化问题 ,利用小波分析在奇异性检测中的优越性 ,将其引入到结构优化计算中。本文分别讨论了小波分析处理低维和高维结构优化问题 ,并给出相应的算法及计算步骤。最后 ,给出较为典型的算例。通过算例表明 ,小波分析方法可解决具有奇异性的结构优化问题 。Wavelet theory is a newly developed analyzing technique that has been successfully applied in many fields such as image processing, signal processing etc. This technique is introduced into the Structural Optimization field, because it has the advantage of singularity detecting. In some special structural optimal problems, it is difficult to find global optimal solution by traditional method, but it is slightly easy to solve this problem by wavelet analysis. In this paper we also give preliminary study about high dimensional structural optimization with wavelet analysis.
