The axle dynamometer simulates the starting acceleration performance test of the axle; Torque performance test; Maximum speed performance test; Coasting performance test and braking force performance test.
Test basis: QC T 534-1999 evaluation index of vehicle drive bridge bench test
Test parameters:
Input voltage (three-phase), current (three-phase), power factor, electric power
Input torque, speed and power
Left end output torque, speed, power
Output torque, speed and power at right end
Efficiency and speed ratio
Vibration and noise
Communicate with the computer to display and store the collected data in real time.
The test data are digitally displayed and can be sent to the computer for sampling, curve drawing and printing, with different language interfaces; Attached figure.
The whole machine has high sensitivity, good load torque stability and test repeatability.
The system is easy to operate, and the load can be changed only by adjusting the excitation current.
The software operation is simple and easy to learn, and can realize manual, automatic, fixed point and other test methods. The test results can be compared with curves, and the data can be imported into Excel.
The system has a manual test mode (this mode can be operated without connecting the computer): that is, the load is manually adjusted, the data is manually recorded or collected, and the data can be locked.
