Abstract

The invention discloses a road condition simulation loading test device and a test method for a driving motor of an electric vehicle. The test device is composed of a strain torque speed sensor, a speed reducer, a transmission device, tires, a power motor, a lifting device and a detection control cabinet. The transmission device, the tires and the power motor constitute a loading platform to simulate various road conditions; a motor lifting platform adjusts the height of the motor; and a computer adjusts the road conditions simulation loading platform to realize realistic road surface simulation on the motor to be tested under different weather, different roughness and different driving modes. By simulating a road with conveyor belts, simulating road roughness with change of the conveyor belts, simulating road slope with lifting adjustment of contact angle between the tires and the conveyor belts through a lifting transmission device and simulating different weather conditions with change of force applied by the power motor, a user inputs road conditions, collects motor power and speed data, processes the data and forms a graphical report to intuitively reflects the performance parameters of the motor and simulated loading effects under different road conditions.

Description

technical field

[0001] The invention relates to the technical field of motor testing, in particular to an electric vehicle drive motor road condition simulation test device and test method. Background technique

[0002] At present, the test device for electric vehicle drive motor is generally composed of loading table, drive motor, motor controller, strain gauge torque tester, power analyzer, data acquisition module, power distribution cabinet, and battery pack. The loading table provides load for the driving motor, and the data acquisition module collects the speed, current and torque information of the driving motor to realize the performance test of the driving motor. The function of this device is relatively simple, and it can only complete the performance test of the driving motor under a specific load, and cannot perform the performance test of the driving motor under different complex road conditions.

[0003] Due to the complex and changeable road conditions of vehi...
