[0002] The role of the comprehensive automotive NVH performance test platform is to help automakers fully understand and improve the noise, vibration and roughness performance of vehicles, thereby improving product quality and user experience.

[0003] Although current technology has many advantages, its disadvantage is that when conducting a comprehensive test on the NVH performance of a car, the car needs to be lifted. However, most current technologies use two hydraulic cylinders to work at the same time. When the two hydraulic cylinders are working, they will consume too much electricity, which increases the cost of the comprehensive test of the car's NVH performance. In addition, when conducting a comprehensive test on the NVH performance of a car, it is necessary to simulate the NVH performance of the car under various road conditions, which will inevitably cause the car to vibrate. Vibration will reduce the service life of the car's NVH performance comprehensive test platform, which is not conducive to the company's sustainable development. Utility Model Content
