Abstract

In diesel engines, it is inevitable that the torsional vibration is produced by the fluctuation of engine torque. Therefore, it is necessary to establish preventive measures to diminish the torsional vibration. A sleeve spring damper is one such measure to reduce the torsional vibration. In this study, the closed form equations to predict the spring constant of a sleeve spring and the dynamic characteristics of the torsional vibration damper are proposed to calculate stiffness of the damper, and verified their availability through the finite element analysis. Our theoretical values are in good agreement with results obtained from finite element analysis and experiments. Results obtained from the derived equation enable designers to be more efficient.
