Abstract: The simulation of coupling dynamics from multi-body movement, flow field and structural stress field plays a significant role in the separation system design for a near space vehicle. In this paper, an elastic-body based multidisciplinary and multi-physics coupling simulation approach is proposed for the vehicle separation process. A multidisciplinary separation simulation system is developed, where the dynamic finite element simulation method for stress field, the high performance numerical simulation method for flow field and the multi-body movement simulation are combined. The proposed simulation system provides an efficient and accurate way to verify the separation scheme and the design of separation systems.
