基于ANSYS 的整体张拉索膜结构荷载响应分析* 1 2 1 张国军 李晓通 张曼生 (1 中国航空规划建设发展有限公司，北京100120；2 北京工业大学，北京100124) [ 摘 要 ] ANSYS 作为工程模拟的大型通用有限元计算软件，经过几十年的发展，在理论和算法上都趋 于成熟，特别是在结构非线性的求解分析方面具有独特的优越性，因此基于ANSYS 的索膜结 构分析和研究越来越受到重视。本文结合某一实际工程的算例分析来阐述ANSYS 软件在整体 张拉索膜结构体系设计研究中的应用。通过分析，揭示了本文中索膜结构体系的静力性能、弹 塑性性能和动力特性，为工程实践提供指导，并证明了ANSYS 能够对索膜结构的承载过程 及其非线性特性进行准确的模拟和计算。 [ 关键词 ] ANSYS ，整体张拉索膜结构，非线性，载荷分析 Loading analysis of All-tension cable-membrane structure based on ANSYS 1 2 1 Zhang Guojun ，Li Xiaotong , Zhang Mansheng (1 China aeronautical Project and Design Institute, Beijing 100120,China； 2 Beijing University of Technology ,Beijing 100124,China ) [ Abstract ] ANSYS, as a large general finite element software in engineering simulation, are becoming more and more mature in the theory and algorithm after decades of development. ANSYS has an unique advantage in the aspect of structure nonlinear analysis; so the analysis and research of cable-membrane structure based on ANSYS are taken seriously. This paper expounds the application of ANSYS in the all-tension cable-membrane structure design and research combining with a practical engineering. The static performance, elastic-plastic performance and dynamic characteristics of the structure are revealed and that will provide guidance for engineering practice. This paper also proves that ANSYS can make accurate simulation and calculation in the loading process and nonlinearity of the cable-membrane structure. [ Keyword ] ANSYS, All-tension cable-membrane
