摘要：

为了探究一体式电子液压制动系统（One Box EHB）中增压阀与减压阀的工作特性，该文提出增压阀与减压阀多物理场耦合的建模与仿真方法，并设计试验台架进行验证。根据增压阀与减压阀的结构和原理，对增压阀和减压阀物理场特性进行建模；对增压阀进行电磁场、流场、运动场多场耦合仿真和试验验证；对减压阀进行了电路、电磁场、运动场场路耦合仿真和试验验证。结果显示：增压阀耦合场仿真模型的流量仿真误差小于1.5 mL/s，减压阀耦合场仿真模型开启延迟时间误差小于1.3 ms，关闭延迟时间误差小于0.3 ms, 表明该仿真方法具有较高的仿真精度，对电磁阀控制具有参考意义。

Abstract:

In order to explore the working characteristics of the pressure boosting valves and pressure reducing valves of the One Box Electro-Hydraulic Braking System (EHB), multi-field-coupled modeling and simulating methods of pressure boosting valves and pressure reducing valves were proposed, and results were verified by innovative testing bench. The structures and working principals of pressure boosting valves and pressure reducing valves were introduced. Each physical characteristic of pressure boosting valves and pressure reducing valves were precisely modeled. Multi-field coupling simulations, including electromagnetic field, flow field, and motion field, and experimental verifications for the pressure boosting valve were conducted. Simulations and experimental verifications were performed for the pressure reducing valve, including electric circuit, electromagnetic field, and motion field. The results show that the simulation error of the flow rate of pressure boosting valve is lower than 1.5 mL/s, the open delay response error of pressure reducing valve is smaller than 1.3 ms, and the close delay response error smaller than 0.3 ms, indicating that the proposed simulation method has a high accuracy, and providing a guidance for the control of the valves.
