반공진을 이용한 대역 차단형 비틀림 진동 절연기의 토크 전달률 해석 및 측정

초록

This study presents the investigation of new type of torsional vibration isolator utilizing an anti-resonance induced by planetary gear sets. This type of torsional isolator generates the anti-resonance frequency capable of effectively attenuating torsional vibration induced by an internal combustion engine those in a specific range. To evaluate its feasibility and isolation performance, the torque transmissibility of both the proposed torsional vibration isolator and the conventional torsional vibration isolator are estimated, and compared. The band-stop frequency can be tuned to achieve wider isolation frequency range. Finally, the proposed torsional vibration isolator was designed, manufactured, and its torque transmissibility, one of the essential vibration isolation performance indicators, was experimentally measured by using a low inertia dynamometer with non-contact torque sensors and then compared with the simulation results of the proposed torsional vibration isolator.
