摘要
在巷道支护结构的有限元分析中,常需要将不同单元组合建模,这就需要考虑单元连接的处理方式。本文讨论了巷道建模中刚性连接(Cerig)、约束方程连接(Cp)及MPC连接的差异,并通过算例进行了对比,总结了各种方法的优缺点及适用范围。
In the finite element analysis of roadway support structure,it is often necessary to model the combination of different elements,which needs to consider the treatment of element connection.In this paper,the differences of rigid connection(Cerig),constraint equation connection(Cp)and MPC connection in roadway modeling are discussed,and the advantages,disadvantages and application scope of various methods are summarized by comparing the examples.
