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

摘要

Continuously variable transmissions (CVTs) contained in many complex systems of modern techniques can be designed as purely mechanical systems that can, thanks to their structure, do self adjustments, meaning they can change their own characteristics in order to adapt to the external parameters variations. In this way adaptive CVT can be used for automatic regulation of a system. A general approach to the dynamical description of adaptive CVT behavior as a nonholonomic, completely mechanical system is developed. For the dynamical description of the mechanical nonholonomic system, Appell`s differential equations are used. By numerically solving differential equations of motion, answers about the working stability as well as the dynamical and kinematic behavior of the observed CVT system are obtained thus proving CVT’s functional applicability as a regulator for a changeable working regime. Presented approach can be used in choosing optimal parameters for the synthesis of this type of transmissions.
