在ANSYS有限元分析中经常会同时使用实体单元与壳单元以满足对结构不同部位的分析要求,这就存在壳与实体单元连接时自由度不匹配的问题.本文通过一个悬臂梁模型,采用几种不同的连接方法进行计算和分析比较,得到了相应结论并给出了几种连接方法的使用建议.

Solid and shell elements are often used simultaneously in ANSYS to meet the analysis requirements of different structure parts. An issue will rise in the connection that the degree of freedom of shell element doesn't match that of solid element. A cantilever beam is used to demonstrate several connection methods available to solve this problem and the analysis results are compared. In the end, some proposals about these methods are put forward.
