Abstract

Abstract: In this paper, according to the requirements of winding molding of heat insulation of the solid rocket motor, the geometric features of variable curvature mandrel and the characteristics of winding molding were analyzed, the winding angle calculation method of variable curvature mandrel and the adaptive control method for rubber tape gaps based on geodesic method were studied to control the winding direction and satisfy the tape gaps requirement. The causes of tearing and wrinkle of the rubber tape were analyzed, and the determination conditions of tearing and wrinkle were established. The distribution of the contact pressure between the heat insulation and the elliptical concave roller was studied, and the winding pressure control method was proposed based on the Winkler model. Based on the above method and geodesic algorithm, the trajectory planning for winding molding of variable curvature rubber heat insulation was fulfilled. Finally, the feasibility of the algorithm was verified by the winding molding simulation of rubber heat insulation. The results show that the algorithm proposed is feasible and can satisfy the requirements of the winding molding of variable curvature rubber heat insulation with excellent effect.
