【摘要】：船用海水泵在工作时产生的振动噪声较大,会影响泵使用性能及危害工作人员身体健康。选择泵体、转子系统、隔离套以及外转子作为分析对象,采用有限元分析方法,利用ANSYS软件对其进行模态分析。通过模态分析得到泵的各个主要零部件的固有频率及振型。对比工作中可能产生的振动频率,确认了泵的系统产生共振的可能性非常小,保证了海水泵工作时的安全性与可靠性。海水泵的模态分析方法为后续进行泵的动力学分析及优化设计提供了参考依据。
[Abstract]:The vibration and noise produced by marine sea water pump in operation will affect the performance of pump and endanger the health of the staff. The pump body, rotor system, isolation sleeve and outer rotor are selected as the analysis objects. The modal analysis of the pump body, rotor system, isolation sleeve and outer rotor is carried out by using the finite element analysis method and ANSYS software. Through modal analysis, the natural frequencies and modes of the main parts of the pump are obtained. By comparing the vibration frequency of the pump system, it is confirmed that the resonance of the pump system is very small, which ensures the safety and reliability of the water pump. The modal analysis method of sea pump provides a reference for the dynamic analysis and optimization design of the pump.
