摘　　要：通过对海水泵系统等效力学模型的构建,描绘出系统从启动到停止全部三个过程海水泵系统的动力随时间变化的规律。建立以回转运动的斜盘为等效构件,以斜盘的摆角作为广义坐标求解所得出的等效转动惯量与等效力矩所构成的等效力学模型,进行动力特性分析。并通过等效构件有效地将整个系统动力特性折算到等效构件上,求解出三个阶段海水泵系统的动力特性。By structuring an equivalent model system of seawater pump,this paper illustrates the law of dynamic changes over time during all the three stages from starting to stopping of the system of seawater pump.Then,an analysis of dynamic characteristics is made on the basis of structuring an equivalent components of rotary swash plate,where an equivalent dynamic model is obtained,consisting of equivalent rotary inertia and equivalent moment which is solved by taking the tilt angle of the swash plate as a general coordinate.Finally,by converting all the effective characteristics of the whole system into the equivalent components,the dynamic characteristics of the seawater pump system are solved.
