A Study on Design of Auto Tension Control Creel Compression Coil Spring for Twister Tensioner

섬유기계의 트위스터용 스프링 텐션 유지를 위한 압축코일 스프링 설계에 관한 연구

A spring tension control device is used as a very important part of an twister system. The friction force of tensioner must keep same friction force during winding in package. For satisfy this function, many device used common compression coil spring. In this paper, by using the case-building technique which was based on simple theory that unknown design variables are induced by given input design variables by the designer, design automation algorithm about rectangular section compression springs with elastic characteristic is developed. Four design equation are justified in using of analysis of torsion of straight bar of rectangular section and geometrical condition of coil spring. Four design equation and nine design variables are computed by case-building technique.
