With the development of light weight design and the high power output of an engine, and since the damping of rubber materials is relatively low, the effectiveness of torsional vibration (TV) control for an engine crankshaft with an ordinary Single Mode and rubber-damped TV Absorber (SMTVA) is limited. Here, a SMTVA references to a TVA with only one inertial mass. In this paper, the configurations of some Multi-Mode and rubber-damped TV Absorbers (MMTVA) having more than one inertial mass are introduced firstly, then a detailed procedure for modeling a torsional vibration system for a generic crankshaft system is presented. Thirdly, an optimization method for determining the design parameters of a MMTVA (mass ratios, frequency ratios and damping ratios) is developed. The proposed calculation method is based on reducing the torsional vibration of a crankshaft. An example is given for demonstrating the effectiveness of the proposed method and the MMTVA in reducing the TV of a crankshaft. The calculated results show that MMTVA can reduce crankshaft TV greatly although the damping of each SMTVA in a MMTVA is provided with the rubber materials.
