JERK ANALYSIS OF D MECHANISM

Crank-rocker mechanism is one of the most important 4-bar mechanisms often used as the main part of path generator mechanisms. D mechanism is a particular type of crank-rocker mechanisms. They’re used to generate paths like letter D. These mechanisms are used vastly in industrial applications and therefore should be kinematically analyzed. Analyzing the mechanisms in various situations, we can determine velocity, acceleration and jerk of the actuator of mechanism. In this paper, we study how the variation of size of all links affects to kinematical parameters of D mechanism. In order to implement our study, we use Matlab as the programming language. As the results show, it’s possible to come to a decision on what size is best for the mechanism In order to control the kinematical parameters not to grow up above a specific threshold
