Dynamic Analysis of Helical Gear System Considering Time-varying Frictional Force

Friction between meshing gears is one of the principal exciting sources of vibration in gears. Numerous literature have been devoted to investigate the influence of friction on the system. In this article, a new analytical model of a gear transmission system with time-varying meshing stiffness, viscous damping and friction torque is studied to examine the significance of sliding friction on system response and stability.
