Torsional Vibration on the Complex Shaft System of a Vehicular Powertrain

建立了履带车辆动力传动系复杂轴系的扭振模型,对车辆动力传动系扭振计算进行了深入研究,为履带车辆动力传动系关键部件的设计及深入研究提供理论依据.针对固有振动和强迫振动计算的特点,利用系统矩阵法,借助Matlab语言及其GUI工具编制了交互式计算程序,并进行了实验验证和整车计算分析.开发程序也可用于船舶等其他复杂动力传动系轴系的扭振研究.

The torsional vibration model of the vehiclular powertrain in a multishaft and complex branch structure is established and further studies are carried out on the method of calculation of torsional vibration problems. The purpose is to supply a theoretical basis for the design of powertrain components and for a further study on their characteristics. Adopting the matrix method, torsional vibrations are calculated. An interfacefriendly torsional vibration analysis software has been developed with Matlab and its GUI toolbox, suitable for the calculation of both free and forced vibrations. Its validation is completed in this paper. The software can also be used for complex powertrains of ships.
