PARAMETRIC OSCILLATIONS OF MULTIPLATE CLUTCHES LINED PLATES OF THE VEHICLE POWERTRAIN
The investigation is dedicated to formation of dynamic loading in vehicle transmission and to justification of the methods to improve multiple clutch lifetime. The hypothesis about friction discs destruction due to influence of disturbance from engine and torque converter is put forward. Conditions of formation for parametric resonant oscillations are determined. The instability areas of discs parametric oscillations are identified in accordance with Mathieu equation and Ince-Strutt diagram. The actions which are aimed to increase lifetime of the discs are suggested. Results of its efficiency estimation are demonstrated.
