摘　　要：推土机转向制动阀是实现推土机转向制动操纵的关键部件,对整机性能有重要影响。本研究首先对转向制动阀的工作原理进行了分析,建立详细的数学模型;然后基于Simulation X软件仿真平台,建立其系统仿真模型,通过对比分析仿真结果与实测参数,验证了仿真模型的准确性。最后研究了各参数变化对系统性能的影响,着重分析了与离合器压力曲线及操纵力相关的性能参数,为今后产品开发设计及性能优化提供了数据参考及理论依据。The Dozer Steering control valve is an important part in Dozer steering and braking control system, and it is also important to the performance of the Dozer. First, the working function of the steering control valve is analyzed. Then, a simulation model of the system is established based on the software SimulationX. The model is verified by the comparison of the simulation results and the test data. At last, each parameter＇ s influence to the pressure curve and the operating force is researched by changing each parameter value. The results build the theory foundation for the valve design and performance rising.
