Abstract

Abstract: This paper introduces the research status of automated winding molding of solid rocket motor heat insulation at home and abroad, proposes the heat insulation winding molding scheme and equipment scheme, and focuses on the key technologies of heat insulation winding molding. According to the characteristics of heat insulation winding molding and the winding pressure control requirements, the winding pressure control method was proposed. By analyzing the causes of winding tape deviation, the tape rectification method was put forward. An elliptical concave roller was designed to ensure the tape edge bonding quality and avoid tape edge warpage. A calculation method of universal tape width for heat insulation winding molding was proposed by analyzing the parameters related to the contact deformation of the rubber tape between the cylindrical roller and the smallest mandrel. According to the requirements and characteristics of tape transport speed and tension control for heat insulation winding molding, the tape transport speed and tension control method was proposed. The dynamic demonstration system of heat insulation winding molding was established to provide support for the development of automated heat insulation winding molding equipment.

Key words: heat insulation, winding molding, pressure control, rectification, elliptical concave roller, composites
