Research On Torsion Vibration Of Vehicle Drivelines Concerning The Jointing Of Frictional Clutch

This article established the dynamics equation basing on analyzing the jointing process of frictional clutch, analyzing the inherent frequency and the response of torsion vibration and the sensitivity of inherent frequency , which is important and useful to analyze the influences of each parameter of vehicle drivelines to torsion vibration and reduce the yawp of starting ,and ameliorate the capability of torsion vibration.On the basic theory of vibration, the vibration characteristic of every proportion of transmission was also studied with traditional points, then brought in trial system of mode analysis and analytic method. The transmission was considered as a system , its vibration characteristic with elasticity coupling was analyzed. To the transmission of two gimbals, its torsion vibration was described in respective mathematical model, to the transmission of three gimbals, it did so;at the same time, their flexible matrix were reasoned out. Further more, small damp model of the transmission with two gimbals was hammered out its bend vibration's state space equation. The dynamic response characteristics of the system was simulated with the imbalance of running engine flywheel or running transmission shaft or maneuver input on the help of the software MATLAB/SIMULINK. According to the modification parameters, the corresponding different result was comparatively analyzed , finally a delicacy analysis method on the basis of structural modification was given out.
