Constant torque load application soft start-up test method

[0023] refer to figure 1 , 3 , constant torque loading soft start test method, the method is in image 3 It is carried out on the test device shown, and the tested equipment is mechanical soft start equipment 2, and the corresponding test steps are as follows:

[0024] 1. Connect the device under test - on the test bench, drive and connect the mechanical soft start device 2 (such as an adjustable hydraulic coupling, etc.) Torque speed sensor;

[0025] 2. Connecting the loading device—the disk-type constant torque loading device 3 and the mechanical soft start device 2 are connected by drive, and another torque speed sensor is arranged on the drive shaft;

[0026] The above-mentioned two torque speed sensors are respectively connected to the recorder, printer, and display in the test system;

[0027] The above-mentioned disc type constant torque loading device 3 includes elastic elements, brake brakes, brake arms, brake connecting rods, brake discs and friction plates, and the
