摘要
Abstract
A theoretical torsional vibration model for the drivetrain of a front-engine-and-rear-wheel-drive (FR) car was built. Torsional vibration modal frequencies were calculated by free vibration analysis and validated by comparing the re-sults with those of torsional vibration test of the car. Based on this model, the sensitivity of the torsional stiffness and mo-ment of inertia of different components to the drivetrain modal frequencies was analyzed. It is shown that the 3rd order mod-al frequency can be tuned by adjusting the torsional stiffness or moment of inertia of the wheels;the 4th order modal frequen-cy can be tuned by adjusting the torsional stiffness or moment of inertia of the wheel or the torsional stiffness of the half shaft;the 5th order modal frequency can be tuned by adjusting the torsional stiffness of the half shaft or the moment of iner-tia of the driving shaft.关键词
