摘要
索网中的预应力分布需要通过形态分析来实现,文章针对找力分析方法-逆迭代法在索网找力中的应用进行研究,通过分析该方法的基本理论和数值算法,基于有限元数值计算软件ANSYS建立逆迭代法的计算流程,以实现逆迭代法的迭代过程,并通过算例进行了验证。算例结果表明:逆迭代法应用于大型索网结构的找力分析是可行的。
The distribution of the prestressed need be through morphological analysis to find. Based on the analysis of method-inverse iteration method, the basic thought and algorithm of the method was analyzed. The inverse iteration method of calculating process is established to realize the iteration of the inverse iteration method based on the finite element numerical simulation software ANSYS, and is verified by an example. The numerical results indicate that the large cable network structure can be obtained through analysis for force satisfies given shape of prestress distribution.
