Missile stage separation simulation considering complex factors

摘要

In this paper, a kinematics and dynamic model of missile stage cold separation process is established. The stage separation of missile is simulated considering the influence of separation motor thrust bias and residual thrust point bias and thrust direction deflection of spent stage. Separate bodies' movement despite deviation interference is obtained. Moreover, Monte-Carlo method is also used to analyzing the range of separation bodies' movement. These results provide a reference for missile separation simulation and interference factors analysis.
