A air-oil coupling shock absorber is designed through coupling the air, oil, rubber and metallic elastic component by ingenious tactics for the demand of resisting violent impact and attenuating vibration in vibration-impact-safety of equipment. The key-model machine shows the strong nonlinear dynamic characteristics in multi-parameter coupling impact test. Based on this,a nonlinear dynamic-impact characteristics model is established through combining the theoretical analysis and the actual structural parameters. Analytic result is illustrated to show that the multi-medium coupling shock absorber has a good dynamic performance and controllable design-capability, thus, it has a broad application prospect.
