Adaptive continuously variable transmission used for maintaining stationary regime of driving machine

Abstract

Continuously variable transmissions (CVT) contained in many complex systems of modern techniques can be designed as purely mechanical systems that due to their structure make self adjustments, meaning they can change their own char-acteristics in order to adapt to external parameters variations. In this way adap-tive CVT can be used for automatic regulation of a system. A general approach to dynamical description of adaptive CVT behaviour as a non-holonomic, com-pletely mechanical system has been developed. For dynamic description of me-chanical non-holonomic system, Appell`s differential equations are used. By nu-merically solving differential equations of motion, answers about the working stability as well as dynamic and kinematic behaviour of the observed CVT system are obtained thus proving CVT functional applicability as a regulator for a changeable working regime. Presented approach can be used in choosing opti-mal parameters for the synthesis of this type of transmissions.
