Modelling and simulation of a Geneva mechanism using Solidworks

AIM:

To model and simulate Geneva mechanism using Solidworks.

OBJECTIVE:

1)To model the driver and driven wheel.

2)To assemble the models.

3)To simulate the assembly from 0-22 seconds.

THEORY:

Geneva mechanism is one of the most commonly used devices for producing intermittent rotary motion, characterized by alternate periods of motion and rest with no reversal in direction. It is also used for indexing (i.e., rotating a shaft through a prescribed angle). In simple words it translates a continuous rotation movement into intermittent rotary motion.

The rotating drive wheel is usually equipped with a pin that reaches into a slot located in the other wheel ( driven wheel ) that advances it by one step at a time.

PROCEDURE:

1)Firstly, the driver wheel is modelled.

2)Then the driven wheel is modelled with respect to the dimensions of the driver wheel.

3)The diver and the driven wheel are assembled together.

4)The material of both the driver and the driven wheel is chosen and the assembly is simulated for a time period of 0-22 seconds.

5)Finally a graph is plotted between time and reaction forces.
