航空救援绞车电液伺服系统仿真研究

Simulation Research of Electro-hydraulic Servo System for Aviation Rescue Winch

分析了航空救援绞车系统的特点及电液伺服控制工作原理。利用AMESim软件,建立了航空救援绞车电液伺服系统的仿真模型,并进行了仿真研究,表明该系统具有较高的提升速度控制精度和良好的速度跟随特性;超载对系统的工作影响显著,在使用中,应避免超载运行。

The character of aviation winch system for rescue and working principle of electro-hydraulic servo control are analyzed. Based on the AMESim software, a simulation model of electro-hydraulic servo system of aviation winch system for rescue is established. Using this model, simulation has been performed and shows that this system has high speed control accuracy and good speed tracking characteristics. And overload make a bad effect on this system, it will be avoided in using.
