Discussions on the Local Torsional Vibration Modes of Automotive Power Train and Analytical Model Simplification of Symmetrically Branched Axle Shaft |
| |
| Abstract: | Two problems of torsional vibration analysis of FR-type automotive power train are investigated: one is the local vibration modes and the corresponding dominant substructures; the other is the modal symmetry and the simplification of analytical model for symmetrically branched axle shaft substructure. The results obtained here are helpful for proper simplification of the analytical model of torsional vibration and a comprehensive understanding of torsional vibration characteristics in automotive power train. |
