The wheel grounding index can represent the working performance of the demand reduction device, the wheel grounding index indicates the minimum ability of the device to ensure the contact between the wheel the road surface. When the vehicle is running, the grounding index of all wheels is different, which is caused by the different working performance of the demand reduction device of each wheel, the load of each wheel, the air pressure of each wheel of the shock absorber bearing of the ATV. If the load of each wheel is consistent with the tire pressure on the test bench, the wheel grounding index mainly depends on the working performance of the shock absorber. Therefore, the working performance of shock absorber can be evaluated by wheel grounding index. In some countries in Europe the United States, the demand reduction device test bench has been widely used to test the working performance of automobile shock absorber. The main manufacturers of the test bench of the demand reduction device used in Europe are Hofmann company of Germany cemb company of Italy. In the process of testing, the vibration damping test bench plate the vehicle under inspection vibrate vertically according to the sine law, the vibration amplitude is fixed the frequency changes. The force sensor senses the vertical force exerted by the wheel on the platen, stores the force signal into the memory. After testing all the wheel damping devices of the whole vehicle, the microcomputer will analyze process the force signal, then the wheel grounding index can be obtained.
