上悬式离心机转子装置的模态分析

Modal Analysis on the Rotor Device of Uphanging Centrifuge

以XJZ1600-N型上悬式离心机转子装置为研究对象,针对转子装置的模态分析问题,建立转子装置的有限元模型,在考虑缓冲胶垫约束的状态下计算了转子装置的低阶模态,获得了转子装置的临界转速。由计算结果可知,离心机的3个生产工艺转速均远离转子装置的临界转速,转子装置的设计满足正常的使用要求,为转子装置的优化改进奠定了基础。

In this paper,the rotor device of XJZ1600-N uphanging centrifuge is taken as the research object,aiming at the modal analysis problem of rotor device,the finite element model of the rotor system is established.Considering the buffer rubber constraint,the low order modes of the rotor device are calculated,and the critical speed of the rotor are obtained.The results show that the three production process speeds of the centrifuge are far away from the critical speed of the rotor device,and design of the rotor device meets the requirements of normal use.It lays a foundation for optimization and improvement of the rotor device.
