Abstract：To study the shock amplification method, combined classical collision theory with dynamic contact theory, created kinematic model of double mass shock amplifier, derived the calculation formula of acceleration and acceleration magnification factor. Studied the effects of collision duration ratio, mass ratio (between the amplifier and the drop-off stage), waveform generator stiffness ratio on acceleration amplification factor. Finally, the theory of two body collision is verified by experiments. The results show that the acceleration magnification ratio decreases with the increase of mass ratio and increases with the increase of waveform generator stiffness ratio and collision duration ratio.
