摘　　要：为解决某风洞柔壁喷管液压系统从高压锁紧状态切换到低压回零工况时执行机构冲击过大的问题,对系统加装卸压控制回路进行改进。基于AMESim建立改进前后系统仿真模型,分别对其工作过程进行模拟分析,同时利用遗传算法对卸压时间进行优化。结果表明,优化后模型在节约能源的同时能有效减小执行机构冲击。To solve the problem that the impact of the actuator is large when the flexible nozzle hydraulic system of wind tunnel switches from lock state in high pressure to zero condition in low pessure,the pressure relief control loop is added to improve the system.The system simulation mode before and after improvements are established based on AMESim to simulate the working process and then genetic algorithm is used to optimize the relief time.Results show that the optimized model can effectively reduce the impact of actuator while saving energy.
