Vehicle which is provided with power split Continuously Variable Transmission (CVT) drive system has been taken as entire car model in this paper, kinetics modeling and simulation analysis of the vehicle has been made progress. Dynamic response of the vehicle has been analyzed based on the wheel rolling resistance, air friction and grade resistance had been considered as total resistance of car driving...
In this paper, the pure torsion vibration model of the planetary gear trains for the increasing gearbox is proposed. The influence coefficient method is used to deduce the system dynamic equations. The dynamic equations are solved considering the variable meshing stiffness and the constant meshing damping. Finally the non-linear dynamic characteristics are analyzed carefully.
The work studies the influences the friction effected the dynamic response of torsional model of gear pair. First, discrete harmonic balance method (DBM) is proposed new method to solve time-varying system dynamic equation; second, nonlinear time-invarying system (NLT) and nonlinear time-varying (NLTV ) system are analysised with friction. Finally, results show that friction is the significance nonlinear...
