Abstract: The dynamics model was established, its corresponding mathematical model by means of modal analysis method was developed. The vibration performance was analyzed with this model. In the condition of rigid impact, the ways of vibration isolation were put forward. The results show that the vibration isolation is valuable in the condition of rigid impact.
