Internal Geneva Mechanism

Aim:-To create the 3D model of the internal Geneva mechanism and study it's motion.

Introduction:-In this Mechanism,I performed 3D modelling of mechanism and done it's Motion analysis for studying its contact forces and plots of angular displacement and angular velocity.

Working:-Working of this mechanism is that continuous rotary motion is converted into intermittent rotary motion.

setup: In this mechanism, we created Driving wheel , Driven Wheel with 4 slots and pin like structure (purple in colour) to drive the mechanism, as per the problem statement.

Result & Explaination:-

Here in this study I had found various plots like contact force with and without precise contact with respect to time,angular displacement ,anugular velocity of driven and driving wheel respectively.where I had seen, when precise contact option was on it take more time to solve and also accuracy of it also increased. and angular displacement of driven wheel was changing with 90 degree after each complete rotation of driving wheel. and angular velocity of driving wheel remains constant throughout the motion.
