本文就旋转电液伺服传动的选择和性能特性做了一般评论。文中用理论和实验数据来说明理想的和实际的伺服传动性能以及各种伺服传动元件(伺服马达、伺服阀、溢流阀等)的选择技术。还考虑了各种异常变量,例如起动压力、管道损失、旁通泄漏、零偏、磁滞、死区和油压缩性对伺服传动性能的影响。 This article made a general comment on the selection and performance characteristics of rotating electrohydraulic servo drives. In this paper, theoretical and experimental data to illustrate the ideal and the actual servo drive performance and a variety of servo-driven components (servo motors, servo valves, relief valves, etc.) the selection of technology. Various unusual variables such as start-up pressure, pipe loss, bypass leakage, zero offset, hysteresis, dead zone, and oil compression are also considered for servo drive performance.
