摘　　要：褶皱问题是高精度空间薄膜结构最关心的问题之一,它是影响薄膜结构形面精度的关键因素.由于薄膜结构褶皱机理的复杂性,该问题一直没能得到很好的解决,人们对褶皱的认识,目前主要是通过试验观察和数值模拟等方法.本文综述了空间薄膜结构褶皱数值研究的发展和现状,并对其中重要的和被广泛采纳的方法进行了重点介绍和评述.最后对褶皱数值分析方法所面临的问题及其发展趋势作了初步展望.Investigation on wrinkles is related with high precision requirements and is one of the hottest topics for space membrane structures. The wrinkles are the key factor to affect the space membrane structural surface accuracy. It is therefore important to develop computationally effective analysis methods to predict the performance of wrinkled membrane structures. At present, the main methods to study the wrinkles in space membrane structures are the numerical simulation and experimental investigation. In the present paper, the recent advances of wrinkle numerical methods for space membrane structures are reviewed. We mainly discuss the important and widely used analytical method of membrane wrinkling, and some suggestions for further investigation are made.
