벨로우즈 굴곡부의 등가보 모델링기법

Bellows is widely used in many industrial fields as it provides a relatively simple means of absorbing mechanical vibration and deformation with its flexibility. In this study, we propose an effective equivalent beam modelling technique of curved bellows to reduce the excessive efforts and costs required for three dimensional shell modelling in vibration analysis of bellows. When this practical technique, based on the strain energy concept, is employed to modify the beam sectional properties of the bellows bend, quite satisfactory results can be obtained.
