4 BAR MECHANISM
A Product Design Homework Assignment
For this assignment, I was given the SolidWorks part files to assemble a 4 bar mechanism. After assembling the mechanism, I had to animate it and generate various graphs pertaining to its motion. All graphs were generated using the data from SolidWorks and Microsoft Excel.
DATA GRAPHS
X-VELOCITY GRAPH
The x-velocity of the extension's midpoint appears to follow a sinusoidal pattern throughout the entire motion.
Y-VELOCITY GRAPH
The y-velocity also appears to follow an oscillatory pattern, but the down-slopes all have a kink in the graph.
MOTOR TORQUE
Maximum Torque: 706.84 Nmm
Crank Angle at Max: 288 degrees
​
Negative torque values indicate a flip in the angular acceleration. This means that the object is slowing down in the motion.
BEARING VERTICAL FORCE GRAPHS
Maximum Vertical Force: 12.79 N (magnitude)
NEW BEARING VERTICAL FORCE GRAPH
Maximum Vertical Force: 10.82 N​
MOTOR POWER AT 600 RPM
Minimum Motor Power: -1262.54 Watts
