- Abstract
In this paper, the explosive is employed to simulate the possible shock waves subjecting to the spacecraft structure. The spacecraft structure is pasted with a layer of soft material so as to alleviate the impact of the shock waves. With the Lagrange finite differential method, the transmitting process of explosive shock waves in the spacecraft structure with the protection of soft material is achieved. Then the analysis of the relationship between the explosive and the impulse density and the influence of the parameters of the soft material on the attenuating effect are given. The results show that the thickness of the explosive is linear to the impulse density, and that the thickness of the soft material and the dynamic volume modulus influence the attenuating effect mostly, which will give theoretical guidance to the protection of the spacecraft structure.
