최적화 기법을 적용한 고속 와인더의 모드해석
Abstract
During the winding process of textile manufacturing, the winder is a piece of core equipment. The high-speed winder in this study reaches high operating speeds of up to 17,000 rpm. The natural frequencies of winder machines by modael testing have been recorded in previous studyies. The purpose of this study is to identify the most effective FE (Finite Element) model through ANSYS, which is one of the commercial CAE programs. ANSYS requires configuration optimization for design variables, such as equivalent stiffness of three different bearings, elastic moduli, and densities of shell and shaft. Through this study, the best FE model for a high-speed winder was obtained using the method of response surface optimization with design variables.
