摘　　要：级间热分离具有改善和提高继续飞行级的稳定性和入轨精度而被固体弹道式导弹广泛采用。以某导弹级间热分离为研究背景建立了分离动态方程,基于ADAMS平台进行了参数化模型的分离动力学仿真分析,协调、选择级间分离的各种参数,阐述了级间热分离需考虑的主要问题。研究表明,虚拟现实技术是实现合理选定导弹级间热分离时序的有效途径,不仅可提高分离系统设计、分析和校核过程中的条理化和清晰度,而且为实现分离系统设计与仿真的精确化、可视化、组合化和通用化提供了较好的基础。the thermal stage separation being provided with improving and enhancing stability and orbit precision for flight was abroad adopted in solid-propellant ballistic missile. In this paper, the separating dynamic equation was built according to thermal separation of multistage missile, the separating dynamic simulation of model was analyzed based on ADAMS, the separating parameters of stage separation were harmonized and chose, considering mostly subjects for thermal separation of multistage missile were described. The researoh shows that virtual reality technology is an availability method to choose sequence for thermal stage separation, and not only to improve consecution and definition for designing, analyzing and checking of separating system, but to provide preferable foundation for realizing precision, visualization, combination and currency of separating system＇ s design and simulation.
