摘　　要：液力式推土机其变速调压阀压力控制特性决定了操作舒适性,某机型推土机存在操作时冲击大的问题,通过Simulation X对该推土机变速调压阀进行仿真分析,获得了调压阀的动态响应特性并改善了推土机的控制性能。The control characteristic of transmission regulating valve determines bulldozer＇ s operation comtort. One type of bulldozer has a problem that it has a big vibration when operators shift gears. This valve is analyzed by SirnulationX, Simulation analysis results can tally well with actual results. Finally the control performance of the bulldozer has been improved.
