摘要
针对空间管路系统振动噪声传递特点提出有限元阻抗分析法的基本思路和计算方法。采用该方法对某典型通海管路系统振动噪声传递特性进行计算并与模型测试结果对比分析,表明该方法正确且满足工程适用要求。
In the paper, the basic idea and computation method for analyzing vibration and noise of spatial piping system based on FEM and impedance analysis are presented. Numerical simulation and experiment of a typical model of pipe system are carried out. The computation method is proved feasible by comparison with experimental result. This method is applicable for engineering design.
