Abstract :
Aiming at the difficult problem to calculate and the joint´s inner force of certain type solid propellant rocket motor´s thrust vector control (TVC)system, which working condition are hard to control and reply, computational fluid dynamics (CFD) combined rigid multibody dynamics (RAD) is applied for numerical calculation on dynamics capability system. The instantaneous thrust of motor was calculated and analyzed, based on that the work resistance of system activity can be got, also the moving regulation and contact force in the joints.
