目前国内通用的电磁摩擦离合器测试方法均为制动法,即在测试时预先将离合器从动侧固定(相当于转动惯量J2=∞),启动驱动电机并带动离合器主动侧旋转,然后接合离合器,通过扭力杆测出被测离合器的动力矩、接通和断开时间等数据,如图1a)所示。制动法只能在离合器主动侧与从动侧相对 Currently the common electromagnetic friction clutch test methods are braking method, which in the test when the clutch driven side of the fixed (equivalent to the moment of inertia J2 = ∞), start the drive motor and drive the active side of the clutch rotation, and then engage the clutch, Through the torsion bar to measure the moment of the measured clutch torque, on and off time and other data, as shown in Figure 1a). Braking method can only be in clutch active side and driven side relative
