Abstract
The torsional vibrations of a crankshaft with three different TVDs are computed based on the origin frequency response function method. This method can quickly predict TVD damping effect. First of all, the torsional vibration damping principle is elaborated and the finite element method for torsional vibration computation based on the integrated parameters is introduced. Then, the modal frequencies of the crankshaft are identified through the torsional modals. And the amplitudes of the torsional vibration of the crankshaft system under the unit torque excitation are distinguished based on the results of the frequency response function. Finally, the torsional vibration acceleration of the crankshaft located in TVD is tested and compared with the simulation results. It is found that the curves of the torsional vibration amplitude by frequency response function method and by the testing are consistent. Furthermore, the interior noise reduction effects of the three kinds of TVD are summarized.关键词
