설계 변수 변화에 따른 고속 와인더의 동특성 해석

Mechanical failure and noise due to vibration are problems associated with a high-speed winder when operated at a higher operation speed at an industrial site. Such a phenomenon is due to resonance owing to the close proximity of the operating speed and natural frequency of the winder. In order to solve this problem, a design to avoid resonance is required. A design is proposed to avoid natural frequencies near the operating speed (17,000 rpm). In this paper, the design parameters of a high-speed winder are defined with a manufacturer. Modal analyses were performed by changing design parameters using ANSYS to obtain the natural frequencies. In order to analyze deformation when a high-speed winder with an unbalanced mass was rotated at the operational speed, simulations for harmonic excitation were performed.
