[0001] The invention relates to the technical field of damping shock absorbers, and in particular to a testing device and a testing method for a vehicle variable damping shock absorber. Background Art

[0002] Shock absorber is an important part of the car, and its performance directly affects the comfort, handling stability and safety of the car. At present, various domestically produced cars, including various models of cars produced by imported technology or Sino-foreign joint ventures, such as Santana, Audi, Fukang, Buick, etc., basically use traditional shock absorbers with fixed damping, which makes it difficult to adapt to different roads and usage conditions.

[0003] There are several problems with the existing detection devices for variable damping shock absorbers: 1.
