Abstract:The paper describes the results of poorly studied interrelated unstable oscillations of friction disks -lateral thermoelastic oscillations perpendicular to the disk plane and parametric oscillations in the plane of the disk

In comparison with other types of transmissions currently used, mechanical continuously variable transmissions are capable of providing significant technical and economic advantages, which makes research in this area relevant. This paper presents a mechanical and mathematical method that allows for studying the dynamic processes that take place during operating a controlled mechanical continuously variable transmission with an elastic element and a one-way clutch which provides for transmitting torque to the driven shaft in one direction only.

Abstract. The paper gives a brief description of a method for predicting dynamic friction disc loading in transport vehicle transmissions due to the occurrence of parametric resonance oscillations. It describes a method for the calculation and experimental determination of the modal characteristics of friction discs. It offers some ways of filtering parametric resonance oscillations.
