摘　　要：高压大流量卸荷阀被广泛应用于矿井作业,由于其结构复杂、关键参数较多,利用控制变量法无法获得最佳的参数组合。为了解决上述问题,分析机械式和电磁式卸荷阀的工作原理,对主要元件进行数学建模和参数设计;在多体动力学仿真软件SimulationX中建立高压大流量卸荷阀的仿真模型,利用BP神经网络训练卸荷阀主要参数与其稳压性能指标ITAE的代理模型,并利用灵敏度分析法寻找对其稳压性能影响较大的关键参数;最终,利用正交试验获取最佳的关键参数组合,并对优化前后的卸荷阀进行性能对比。结果表明:相较初始参数,使用所提性能优化方法后,卸荷阀的稳压性能提高了53.77%,验证了所提方案的可行性。The unloading valve with high pressure and large flow rate is widely used in mine operation,however,due to its complex structure and many key parameters,the optimal parameter combination cannot be obtained by using control variable method.To address the above problems,the working principle of the mechanical and electromagnetic unloading valves was analyzed,and the mathematical modeling and parameter design of the main components were performed.The simulation model of unloading valve with high pressure and large flow rate was established in the multi-body dynamics simulation software SimulationX.BP neural network was used to train the agent model between the main parameters of the unloading valve and its pressure regulating performance index ITAE.In addition,sensitivity analysis method was used to find the key parameters that had the greatest influence on its pressure regulating performance.Finally,the optimal combination of key parameters was obtained by orthogonal test.The results show that compared with the original parameters,the pressure regulating performance of the unloading valve is improved by 53.77%with the proposed performance optimization method,which verifies the feasibility of the proposed scheme.
