Use the Strength Calculation dialog box to calculate the strength of the shaft at a point that you specify. The calculation is performed according to the DIN or ANSI standard. The factors of safety guarding against fatigue failure and against yield point are also calculated.
|
Calculation Standard Specifies the algorithm for calculating strength, and safety factors. |
||
|
Notch tab Specifies details of the selected position, particularly details of objects such as notches, necks, holes, and keyways, which can cause stress concentration. |
||
|
Geometry of Notch Specifies geometric properties of the selected position. If the shaft was created using the shaft generator, the system picks up the geometric details automatically. If the shaft was not created by the shaft generator, or the detected shape is not correct, click the button showing the thumbnail of the geometry to select another shape. The geometric properties change with the shape you select. |
||
|
Set Values from Contour Removes any geometric properties you entered and reverts their values to the automatically detected values. |
||
|
Surface of Notch Specifies the properties of the surface that affect the fatigue strength of the shaft. |
||
|
Surface Finish Specifies the method of machining of the surface. |
||
|
Rz Specifies the maximum roughness depth at the specified point. |
||
|
Loads and Stresses tab Displays a list of forces and stresses acting at the specified point. |
||
|
User Changes Enables the ability to override the calculated values of the forces and moments acting on the specified point. You typically specify these values to perform "what-if analysis" and examine the impact on safety factors and stresses. |
||
|
Constant Value of Specifies how to process fatigue failure. |
||
|
Middle Stress Applies the fatigue factors only to alternating stresses. You typically apply this method when the mean stress is not high. |
||
|
Middle/Amplitude Stress Applies the fatigue factors to both mean and alternating stresses. |
||
|
Fatigue Factors tab Displays a list of factors that influence the fatigue failure calculations. |
||
|
User Changes Enables the ability to override the default or calculated values so that you can perform "what-if analysis" and examine their impact on safety factors. |
||
|
Yield Factors tab Displays a list of factors that influence the yield point calculations. |
||
|
User Changes Enables the ability to override the default values so that you can perform "what-if analysis" and examine their impact on safety factors. |
