摘要
计算力学领域柔软弹性结构的非线性分析是特别复杂的课题 ,更加困难与令人易于受挫的研究方向就是柔软弹性结构在各种复杂外力作用下的成形分析 (Form Finding)或者平衡构形曲线的寻找。迄今为止的研究者大都局限于周边固定约束下求解柔软弹性结构的平衡曲线 ,因此其计算方法不具备广泛适用性。本文提出的动边界支座位移非线性迭代法成功地解决了这一问题 ,在工程上具有重要的应用价值。
The nonlinear analysis of space configuration of flexible elasto-structure is especially complicated, the more perplexing and frustrating research direction is to find and equilibrium configuration of flexible elasto-structure under complicated external loads. Current methods of finding equilibrium configuration was restrictedly to solve mathematic equation under fixed restrained boundary conditions, therefore the adaptation of the computing methods is limimed. This paper presents the nonlinear iteration method of compeling displacement of boundary support, which can succeed flexibly in finding equilibrium configuration under complicated external loads.
