ANSYS - Crank - Step 4

Step 6: Setup (Physics)

We have two loading conditions to specify. First we must fix the hole where the crank would attach to the bicycle. Then we apply our loading condition of 100 lb on the end of the shaft.

Fixed Support

Under Outline, right click on Static Structural (F5), move the mouse cursor to Insert and select Fixed Support.

Now in the Graphics area, select the cylindrical hole and click Apply next to the Geometry under Details of "Fixed Support".
 

Force on Shaft

Now we will apply 100 lb force at the end of the shaft. This time, I will show you another way of inserting boundary condition.

Under Outline, left click on Static Structural (F5). Third menu at the top will show different type of boundary conditions. Left click on Loads and select Force. In the Graphics window, select the circular area at the end of the shaft. Under Details of "Force", click Apply next to Geometry. The selected area in the Graphics window will be applied with this boundary condition. Next we will enter the value of 100 lb force. Next to Define By, change Vector to Components. Enter a value of -100 next to Y Component. In the Graphics window, you will see the direction of force applied.

 
Congratulations! We are done setting up the boundary conditions.
