摘　　要：文中以某导弹发射装置液压系统中的伺服阀内漏故障为例,介绍容积效应对液压系统的影响。通过对某型伺服阀出现内漏超差分析,确定是由于伺服阀控制腔连接管路过长及液压管路容积效应的影响,使得控制腔连接管路中的油液体积变大,从而导致伺服阀内漏超差。经实际分析,提出减小伺服阀控制腔管路体积,通过仿真及试验,伺服阀内漏满足指标要求。从而说明了容积效应对导弹发射装置液压系统性能有一定的影响。The influence of volume effect on hydraulic system was studied based on the inner leakage fault of servo valve in missile launching device hydraulic system. According to servo valve leakage error,the error is due to overlong connecting pipe in the control cavity and hydraulic pipeline volume effect,which makes oil volume in the connecting pipe of control cavity become larger and lead to an increase of inner leakage. Through the practical analysis,it is proved that the leakage index of servo valve can reach standard requirements by reducing the volume of the connecting pipe in the control cavity. This illustrates volume effect has certain influence on the performance of hydraulic system.
