Analysis of the influence of dynamic load of sea water pump on vibration isolation system based on frequency response function method

为掌握海水泵运行时对隔振系统的影响,本文采用传递函数计算方法,利用实际海水泵的参数及实测得到的隔振元件机械阻抗参数,针对轴系海水系统海水泵的运行参数进行模拟计算。计算结果表明,海水泵运行会对隔振系统产生一定的位移影响,但不会影响隔振系统隔振效果的发挥。

In order to master the Influence of sea pump operation on vibration isolation system, this paper adopts the transfer function calculation method, using the actual sea pump parameters and the measured mechanical impedance parameters of vibration isolation element, for the operation parameters of sea water pump in shafting system. The calculation results show that the operation of sea water pump will have a certain displacement effect on the vibration isolation system, but it will not affect the performance of the vibration isolation system.
