安全壳喷淋泵的模态分析与试验验证

Model Analysis and Experimental Verification of Containment Spray Pump

利用ANSYS有限元程序对安全壳喷淋泵进行模态分析,获得该结构的自振频率和振型;对安全壳喷淋泵进行动力特性测试并与分析结构进行比较。结果表明:理论计算的自振频率和振型与试验结果吻合较好,验证了该模型的有效性。

Modal analysis of the containment spray pump is carded out by using ANSYS program, and structural natural frequencies and modes of vibration can be obtained. After that, the dynamic characteristic test is performed for the containment spray pump. The comparison between modal analysis results and test results show that they agree well. It verifies the validity of the model and lays the foundation for the structural integrity analysis of the containment spray pump.
