This paper describes a new type of shock absorber which is based on Solid And Liquid- Mixture (SALiM). The SALiM is composed of incompressible liquid and many compressible hollow rubber spheres. When under shocks, the incompressible liquid can instantly pass the pressure on to all the hollow rubber spheres in the container of the shock absorber, which causes all the hollow rubber spheres compressed and deformed simultaneously. As a result it could greatly absorb and dissipate the energy of shocks. Therefore, if designed properly, the shock absorber could have an excellent performance on shock absorbing. The equation of motion of a signal DOF system with a SALiM shock absorber is established. The time response of the system is evaluated and compared with the measured with satisfaction. The displacement power spectrum of the shock absorber under different impact levels is analyzed, and the effect of the shock absorber parameters on its performance is also investigated.
