摘　　要：根据海水液压泵组结构建立了简化的有阻尼两自由度振动力学模型,通过对模型解析,得出了泵组单位作用力位移响应幅频特性和相频特性。以单位激振力作用下的泵组振动烈度为目标函数,运用最优化理论对泵组结构进行了参数优化,为泵组结构参数的减振设计提供了理论依据。Base on the structure of a seawater hydraulic pump package, the simplified vibration dynamic model with damping and double freedom degrees was set up. By solving the model, the displacement amplitude and phase frequency response characteristics under unit force were obtained. Taking the vibration intensity of the pump package under unit force as the target function, the structure parameters were optimized based on optimum design theory, which provides theory evidence for minishing the vibration of pump package.
