摘　　要：本文建立了某高机动雷达液压系统计算模型,对液压系统水锤现象进行分析得到了临界时间以及压力峰值随液压动作时间的变化规律;探究了液压系统管径、工作压力等参数对其临界时间和压力峰值的影响规律,结果表明:在本文研究的范围内,压力峰值随着管径的增大而减小;随着工作压力的增大,系统压力峰值逐渐增大;最后对管径、系统工作压力和换向阀动作时间进行优化,开启和关闭阀门时压力峰值分别从4MPa和6MPa降低至2.1MPa和2.8MPa。A model of the hydraulic system of a high mobility radar was established.The phenomenon of hydraulic shock was analyzed,and the variation principle of critical time and pressure peak with hydraulic action was obtained.The result showed that,within the scope of this study,the pressure peak decreased when the pipe diameter increased,and the pressure peak of the system increased when the operation pressure increased.Finally,the pipe diameter,system operation pressure and action time of reversing valves were optimized,and the pressure peak reduced from 4MPa and 6MPa to 2.1MPa and 2.8MPa respectively when open and close the valve.
