摘要

针对工程广泛应用的圆柱壳结构,首次运用解析法探讨了边界元软件Sysnoise两种加载方式—基于单元(Element)加载和基于节点(Node)加载—对声辐射影响,以及两种加载方式在网格加密情况下的收敛性问题。得到一些对工程计算的有益结论:① 基于单元(Element)加载方式得到的结果要好于基于节点(Node)加载方式;② 基于单元(Element)加载方式网格加密时收敛到解析解,而基于节点(Node)加载方式网格加密后,不一定得到收敛结果。

Abstract

The influence of two loading forms of BEM (Boundary Element Method) software Sysnoise, based on Element and based on Node, to sound radiation, and the convergence of two loading forms when refining the mesh are firstly investigated by analytical solution for cylindrical shell. And some conclusions are obtained: ① the result based on loading form of element is better to the result based on loading form of node; ② the result based on loading form of element when refining the mesh is convergence while the result based on loading form of node when refining the mesh is uncertain.
