Abstract

In view of the problem about the dynamic contact of joint boll-socket nozzle some solid rocket motor, the contact array parameter is determined based on Johnson theory. By virtue of ADAMS software, the positive ball is divided into multi-flexible and connected by dummy part and then the rigid-flexible multi-body dynamics coupling modeling is set up. The distributed force of the joint dynamic contact and the displacement of swing center is computed and analyzed in order to lay the foundation of the pre-research on some solid socket motor.
