摘要
实际工程中的管路系统十分复杂并且含有许多管卡支撑结构,在对管路系统进行有限元分析时,对实际管卡结构进行数值等效简化可以极大地减小有限元分析的计算量。在ANSYS Workbench中主要采用2种方法对管卡进行数值等效简化,分别为离散弹簧支撑和连续弹性支撑。文中详细介绍了在ANSYS Workbench平台中对管道设置实际管卡支撑、离散弹簧支撑和连续弹性支撑,并分别对管道进行了模态分析和静力学分析,对比分析了不同的弹性支撑边界条件下结果的差异。通过有限元分析的计算结果可以看出,采用连续弹性支撑方式可以较好地模拟实际管卡结构。
The pipeline system in the actual project is very complex and contains many pipe clamp supporting structures.In the finite element analysis of the pipeline system,the numerical equivalent simplification of the actual pipe clamp structure can greatly reduce the amount of calculation in the finite element analysis.In ANSYS Workbench,two methods were mainly used for numerical equivalent simplification of pipe clamps,they were discrete spring support and continuous elastic support respectively.This paper introduced in detail the methods of applying actual pipe clamp support,discrete spring support and continuous elastic support to the pipeline in the ANSYS Workbench platform,carried out modal analysis and static analysis on the pipeline respectively,and compared and analyzed the differences of results under different elastic support boundary conditions.Through the calculation results of finite element analysis,it can be seen that the continuous elastic support can better simulate the actual pipe clamp structure.
