摘要
在惯性台架试验机上,根据原来飞轮转动惯量系统产生制动后转速的变化规律,通过计算机实时采集主轴转速、制动压力、制动转矩及制动距离等参数,利用直流电动机及其四象限调速系统,结合转动惯量电模拟控制算法实时控制转速的变化,实现了利用小飞轮来模拟机械系统中较大转动惯量,从而减小传统的机械飞轮。应用机械惯量和电惯量混合模拟的方法实现了惯量的无级调整。
According to the changing law of the rotational speed after original flywheels rotational inertia system produced a brake, in this work, computer was used to gather real-time parameters of spindle speed, brake pressure, brake torque, brake distance ect. With the help of direct current motor and four-quadrant speed regulation system combined with the control algorithm of electrical simulation system for mechanical rotational inertia, simulating the larger moment of inertia by making use of small mechanical flywheel system was realized. As a result, the reduction of traditional mechanical flywheel was accomplished and the stepless adjustment of inertia was realized by the application of mechanical inertia and electric inertia hybrid simulation method.
