Abstract

The article substantiates the ways of tuning parametric oscillations providing for increasing durability of steel and friction plates of vehicle transmissions. The evaluation of dynamic stability is conducted on the basis of the analysis of Mathieu equation and Ince-Strutt diagram. It is offered to restrict the parameter of rigidity modulation depth by filtering low-frequency disturbances formed in the nonlinear system by the power unit (internal combustion engine (ICE) or electric motor (EM)), by hydrodynamic processes in the hydraulic transformer (torque converter or hydraulic coupling) and in the system of its oil supply. The performance evaluation of the developed actions on plate’s durability is conducted.
