摘　　要：针对某型升挂车举升机构液压系统使用中存在的若干问题,采用压力补偿和平衡阀技术对其进行优化设计及改造,同时对改造后的液压系统进行压强特性、速度特性、能耗、锁紧性能和控制性能分析。试验结果证明,改造后液压系统在压强特性、速度刚度、能量耗消和控制精度方面均有较大程度的改善。This paper optimize and rebuild the old hydraulic system of rising mechanism for loader by introducing the pressure compensation and balance valve technology, and analyse pressure characteristics, speed characteristics, energy consumption and control performance to new hydraulic system. Test shows that the pressure characteristics, speed stiffness, energy consumption,locking effect and control precision of new hydraulic system are greatly improved.
