摘要
本文采用样条有限条法计算圆柱壳问题,在边界条件处理上,比半解析有限条法更为灵活,只要对围绕边界点的几个局部样条进行修改,就可以适应任意规定的边界条件。与通用的有限元法相比,它具有计算量小、精度高、应用方便等优点,容易在微型机、袖珍机上实现。
Spline finite strip method for static analysis of cylinder shells has been developed in this paper. In handling the boundary condition, it is more agile than finite strip method. It suits arbitary boundary condition, provided a few splines around the boundary points can be changed, Compared with the finite element analysis, the method has greatly reduced the computational efforts and readily fulfilled the accuracy requiremets, and it can conveniently be carried out on a micro-computer.
