摘要: 临近空间飞行器分离过程涉及多体运动—非线性气动流场-结构应力场耦合特性,对分离方案的设计带来极大挑战。基于高精度分离过程仿真的实际需求以及目前的刚体动力学仿真模型的缺陷,研究了基于动力有限元的弹性体分离过程仿真建模方法,并考虑分离过程中气动流场、应力场与多体运动的耦合作用的仿真求解和高效数值模拟技术,建立了临近空间飞行器分离过程多学科耦合仿真试验系统,为分离方案提供了验证平台,并作为分离系统设计的重要依据。

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.

Key words: near space, multi-body movement simulation, multidisciplinary, multi-physics, coupling
