7.3 Kinematic Analysis

Analysis Without Cam

Animation of Motion

Our team plans to have a motor to rotate link 4 and the cocktail shaker would sit where links 7 and 8 meet. 

Mobility Calculation

Our system was found to have a mobility of 1.

Acceleration Analysis Plot

We performed an acceleration analysis of the end point on our linkage to ensure that the acceleration would be high enough at the direction change for adequate cocktail mixing.

This is the most important aspect of our mechanism.

Analysis With Cam

Animation of Motion

This motion-gen animation uses a crank to mimic the desired cam motion. With the addition of the crank, the linkage can create a motion path that is closer to that of a bartender shaking a cocktail shaker.

Mobility Calculation

The linkage combined with a cam has 2 degrees of freedom.
