Ф4米直升机风洞试验台动力系统研制

The Development of Φ4m Helicopter W.T Test Rig’s Drive System

动力系统是Ф4m直升机旋翼机身组合模型试验台的关键子系统,主要由150kW高速中频电机、控制器和控制计算机等组成。对整套系统来说,转速闭环控制的实现及变频器参数的调整、远程监控的实现是其关键技术,这些关键技术的解决及系统的调试,使系统具备了调速范围宽、机械特性硬、精度高及运行可靠等优点,达到了研制的目的。

The Φ4m helicopter W.T test rig’s drive system is the key sub-system of the test rig.It is composed of electromotor,transducer of intermediate frequency,control computer,and so on.The main techniques involved in this project includes of the realization of rev-closed loop,the adjustment of the transducer parameter,the long-range watching and controlling.Those techniques has realized successfully.So the system has some excellence such as:the timing range is wide,the mechanical characteristic is rigidity,the p...
