A 6-DOF simulation method for emergent separation between the escape vehicle and the carrier rocket is presented based on MATLAB/Simulink. The mathematical and the dynamics model of the emergent separation is established. The 6-DOF simulation of the separation between the escape vehicle and the carrier rocket under the special initial conditions is conducted by Matlab/Simulink with simulation. Results show that the simulation method of the emergent separation based on Matlab/Simulink is feasible. The primary reference for the conceptual design of the escape vehicle is provided by analyzing the thrust of the escape main engine and the structural elastic deformation of the escape tower.
