| Abstract: | The steering brake valve is an important hydraulic component that realizes the steering brake operation of the crawler hydraulic bulldozer. The control performance of the steering brake valve has an important influence on the handling performance of the whole machine. First, the structure and working principle of the steering brake valve are analyzed and introduced in detail, and the mathematical model in the working process is established. Based on SimulationX software simulation platform, the simulation model is established. The influence of different structural parameters on the performance of steering brake valve is studied.The influence of key influence factors on the steering brake valve performance is also studied. And draws an important point to provide a theoretical reference for the structural design and performance optimization of the steering brake valve. |
