It is of great significance to study safety and reliability of test equipment in real destruction performance and strong detonation field. In this paper, a small tactical missile was taken as a model and ANSYS simulation tools were adopted. Based on analyzing force situation of testing equipment during warhead exploding, the dynamic response of the test equipment was studied when adopting aluminum foam material and rubber materials as cushioning material. It was shown that the test equipment will bear 0.037 Mbar pressure of value without any protection, which obviously goes beyond the anti-impact application targets of normal test equipment. But after adopting cushioning material for protection, the aluminum foam can reduce the pressure to 330bar and the rubber can put down the pressure to 4500bar. The result shows that cushioning property of foam aluminum is significantly higher than rubber.
