Shaft Analysis

VectorWorks Machine Design includes a utility to analyze the results of a twisting moment being applied to a round solid or hollow shaft.

To perform the analysis:

1.	Select Machine Design > Shaft Analysis.

The Shaft Analysis dialog box opens.

2.	Enter the shaft properties and the known value in the Solutions section. To add to the list of available units, see Adding User-defined Information to Commands.

 

Parameter	Description
Shaft Analysis	Enter the shaft properties; the analysis results are based on the properties provided
Outside Diameter	Enter the outside diameter of the shaft; select the desired units from the menu
Inside Diameter	Enter the inside diameter of the shaft; enter zero for a solid shaft
Polar Moment of Inertia	Automatically calculated from the outside and inside diameters
Length	Enter the length of the shaft
Shear Modulus	Enter the value of the shear modulus; select the desired units from the menu
Solutions	Select and enter the known value
Twisting Moment	Enter the twisting moment; select the desired units from the menu
Maximum Shear Stress	Enter the maximum shear stress; the units are set by the Shear Modulus value
Angle of Twist	Enter the angle of twist in degrees

3.	Click Solve.

The unknown values in the Solutions section are solved based on the information given.

4.	Click Close to exit the shaft analysis calculator.
