摘要
针对某亚跨超声速风洞复杂的安全关车工况,设计了一种基于组态方式的风洞安全关车控制方法,通过灵活组态调压阀压力调节、模型迎角回零以及调压阀关闭功能模块,形成5种运行工况对应的安全关车控制策略;经调试运行:各功能模块能够实现设计功能,稳定段总压控制精度为0.2%,满足压力控制精度要求;安全关车控制策略可以在异常报警情况下实现压力调节,模型迎角回零以及调压阀关闭,完成安全关车,保证风洞安全。
Aiming at the complex safety shutdown conditions of the transonic and supersonic wind tunnel,a safety shutdown control method based on configuration was designed.By flexible configuration function module of pressure regulating valve,model angle of attack zeroing and pressure regulating valve closing,a safety shutdown control strategy corresponding to five operating conditions was formed.After debugging and running:each function module can realize the designed function,the total pressure control precision of the stable section is 0.2%,meeting the requirement of pressure control precision;in the case of abnormal alarm,the control strategy of safety shutdown can realize pressure adjustment,return model angle of attack to zero and close pressure regulating valve to complete the safety shutdown,ensure safety of the wind tunnel.
