A Study on Design of a Damper for Reducing Torsional Vibrations of a Driveline with Universal Joints

Universal Joint를 갖는 구동축 시스템의 비틀림 진동 감소를 위한 Damper의 적정설계에 관한 연구

A universal joint is a connecting device of two hinges which can transmit torque from one shaft to another at fixed or at varying angles of intersection. It has been used properly not only as rotational but also as intermittent motion. For the particular kinematics condition of a universal joint, torsional and bending vibrations are produced excessively in an elastic driveline. In this paper only the torsional vibration behavior of a driveline with universal joints is analyzed numerically with the discrete model and a design method of the dynamic vibration damper is proposed, in order to reduce torsional vibrations especially in resonance region as a result of parametric variation.
