摘　　要：本文探讨FR式汽车动力传动系扭振的局部模态及其主导子结构和半轴子结构对称分支的模态对称性与模型简化问题,在这两方面取得了一些新的认识,有助于对这类汽车动力传动系扭振分析模型的合理简化和对扭振特性的深入认识。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.
