Optimization of Kinematic Characteristics of Geneva Mechanism

Abstract

In this paper, the possibility of introducing variable angular velocity of a driving wheel is considered, with the purpose of optimization of kinematical characteristics of Geneva mechanism. The purpose is to reduce the rise that occurs at angular acceleration of Geneva wheel during engagement and disengagement, while angular velocity of the driving wheel remains limited. Kinematical analysis of this mechanism is performed. Expressions for angular velocity and angular acceleration of Geneva wheel are obtained. Optimization of the polynomial parameters of the law of the rotation angle of the driving wheel is performed.
