The vibration sensor 44 and the noise monitor 42 are used for testing to test the vibration amplitude and frequency of the new energy power drive mechanism 2 and the noise level of the new energy power drive mechanism 2 during operation. The test data is compared and analyzed by the vibration and noise monitoring device 45 to evaluate the vibration and noise performance of the new energy power drive mechanism 2.

The temperature of the new energy power drive mechanism 2 is detected in real time through multiple sets of infrared temperature sensors 52. If the temperature is too high, the air cooling mechanism 3 is immediately activated to dissipate heat over a large area.

[0083] The vibration and noise monitoring device 45 of the vibration and noise monitoring mechanism 4 is firmly installed under the platform end plate 1 through the mounting plate 451, and the support ring plate 41 is firmly installed on both sides of the platform end plate 1 through multiple groups of support rod brackets 43. Power is supplied to two groups of vibration sensors 44 and multiple groups of noise monitors 42 through the vibration and noise monitoring device 45 to detect the noise and vibration of the new energy power drive mechanism 2 in real time;

[0084] Then, the speed monitoring mechanism 6, the torque monitoring mechanism 7 and the brake locking mechanism 8 are installed above the extension plate 11 respectively;

[0085] The new energy power drive mechanism 2 is started to automatically control the rotation of the drive shaft 21. The plurality of speed sensors 64 measure the speed of the drive shaft 21 in real time and display it above the speed monitoring device 66.

By simulating various load conditions, the stability and efficiency of power output can be comprehensively analyzed. The brake locking mechanism 8, located at the end of the drive shaft 21, quickly and smoothly locks the drive shaft 21 when needed to prevent accidental rotation, ensuring a safe and controllable test process. It also brakes the drive shaft 21 to test the driving performance of the new energy power drive mechanism 2, enhancing the versatility and adaptability of the test. This significantly reduces manual intervention and data processing time, improves test efficiency, reduces maintenance costs, and ensures the long-term stable operation of the test bench.
