| 摘 要： | 对风机风量调整集成式机液伺服液压缸的动态性能进行了研究。分别从改变机液伺服阀芯的阀口面积梯度以及系统泄漏量等方面对集成式机液伺服液压缸的结构参数进行优化分析。仿真分析结果表明:将机液伺服阀芯面积梯度维持在0.5 m或将系统泄漏系数增加到3×10-9,能够提高系统的响应速度且系统有较好的稳定性,系统获得良好的动态特性。

| Abstract: | The dynamic performance of the integrated mechanical-hydraulic servo cylinder for fan air volume regulation was studied. The structural parameters of the integrated mechanical-hydraulic servo cylinder were optimized from the aspects of changing the valve port area gradient of the mechanicalhydraulic servo valve core and the system leakage. The simulation results show that increasing the area gradient of the mechanical hydraulic servo valve core to 0.5 m or the leakage coefficient of the system to 3×10-9 can improve the response speed of the system and the system has good stability,and the system has good dynamic characteristics. |
