Research on Co-Simulation Method with Stability Control and Separation of Launch Vehicle

The stage-separation of launch vehicle is a long distance separation. Up-stage stability control force has remarkable impact on separation-space,and co-simulation with stability control and separation is needed in separation design. Based on CAD / CAE tools,the co-simulation modeling method and simulation process was researched,and the launch vehicle attitude control and separation joint simulation modeling method and simulation process were analyzed,which the fast modeling of rocket separation and attitude control and 3 D visualization separation simulation were achieved,which provides a strong support for accurate predictor and the simulation analysis of separation process.
