The shock absorber performance test standard is a set of specifications and guidelines for evaluating the performance of shock absorbers under various working conditions. It covers the requirements for multiple performance aspects of shock absorbers, test methods, and the basis for judging whether they are qualified or not.

I. Performance parameter related
Load (m): This is the magnitude of the force that the shock absorber is subjected to, usually in kilograms (kg) or Newtons (N). For example, in automobile shock absorbers, the load that the shock absorber needs to withstand should be considered based on the weight of the vehicle, the number of passengers, and the weight of the cargo that may be carried. Shock absorbers of different types and uses have different load requirements. For example, large shock absorbers on industrial equipment may need to withstand several tons of load, while small electronic equipment shock absorbers may only need to withstand a few kilograms of load.

Stiffness (k): reflects the ability of the shock absorber to resist deformation when subjected to external forces. For rubber shock absorbers, stiffness is divided into static stiffness, dynamic stiffness, and impact stiffness. Static stiffness is the force-deformation relationship obtained under slow loading; dynamic stiffness is the vibration stiffness under a certain amplitude and frequency alternating load; impact stiffness is the stiffness characteristic when subjected to impact load. For example, in the shock absorption of some precision instruments, the stiffness of the shock absorber needs to be precisely controlled to protect the instrument from the influence of small vibrations.

Damping (C): It is a key parameter to measure the energy absorption capacity of the shock absorber. The higher the damping coefficient, the more energy the shock absorber absorbs, and the better the shock absorption effect. For example, when the wheels encounter bumps during the driving of a car, the damping characteristics of the shock absorber determine how quickly it can convert vibration energy into other forms of energy such as heat energy, thereby reducing the shaking of the car body.

2. Performance requirements related
Durability: The shock absorber needs to maintain stable performance during long-term use. For example, the shock absorber of a car may need to continue to work effectively while the vehicle travels hundreds of thousands or even millions of kilometers. This requires setting corresponding durability test items in the test standard to simulate the performance changes of the shock absorber under conditions such as long-term vibration, different road conditions and ambient temperature.

Stability: Under different working temperature, humidity, vibration frequency and other conditions, the fluctuation range of the shock absorber's performance parameters should be within the specified range. For example, in the aerospace field, the shock absorber must maintain stable shock absorption performance under extreme temperature changes (from low temperature in space to high temperature in the atmosphere) and complex vibration environments to ensure the normal operation of aircraft equipment.
