in the aviation field, due to limited space and the requirement of high precision and high stability of the equipment, the wave spring just meets these requirements. during the takeoff and landing of the aircraft, the wings and fuselage experience severe vibrations and shocks. in order to reduce the impact of vibration and shock on the aircraft structure, shock absorbers need to be added to the structure. as a shock absorber, the wave spring can absorb vibration energy by using its own deformation to protect the aircraft structure.
