The vibration ripper for crush a rock is a attachment which is mounted to a excavator. As a major component, gear box consists of two eccentric shafts. And this generates the vibration for crushing a rock. The Tooth, a component of vibration ripper, crush the rock by passing the vibration directly to the rock. So, the tooth need the high strength and wear resistance. In this study, we want to confirm the stiffness depend on the shape of tooth, when the impact occurs.
