Experimental research on a coupling shock absorber for reinforcement of electronic-packaging component or MEMS

A multi-medium micro-coupling shock absorber is designed through coupling the air, oil, rubber and metallic elastic component by ingenious tactics for the demands of resisting violent impact and attenuating vibration in vibration-impact-safety of electronic-packaging components or MEMS. Multi-parameter coupling experimental study of the impact mechanical characteristics of the coupling shock absorber is developed. The results show that the key-model machine has a good performance for resisting violent impact and strongly nonlinear dynamic characteristics. The controllable design-capability of the shock absorber is studied by changing of the parameters. So the research results lay an experimental base for future research of engineering design for resisting violent impact in vibration-impact-safety of electronic-packaging components or MEMS.
