Shaft Component Generator Dialog Box - Graphs Tab

The Graphs tab displays diagrams of individual calculated characteristics. Some of the graphs are available for the YZ and XZ planes, and for the sum value.

Access

Shear Stress

Shear strYZ Plane shearess sum.

YZ Plane shear stress in the YZ plane.

XZ Plane shear stress in the XZ plane.

Torsion Stress

Torsion stress.

Tension Stress

Ideal Diameter

The graph shows that an ideal shape of the shaft is based on the bending moment and calculates a diameter of a circular section resulting in a 50MPa stress in every coordinate of the shaft. This graph is independent on the selected shaft material. It shows the overall relations of the shape based on some constant stress.

Depending on the settings, the relevant graphs in the YZ plane (and the sum graphs as well) may include the effect of gravity and material density.

Deflection angle is the angle between the Z axis and the direction of the deflected center line at the given Z coordinate.

The formula for reduced stress is listed in the Engineer's Handbook.

Graph

Displays diagram of selected graph.

Double-click the graphical representation of graph or support to display appropriate edit dialog box where you can change values of load and support. However, you cannot delete loads and supports on the Graphs tab, you can do it in the Calculation tab only.

Results

To display the Results area on the right side of the Graphs tabs, double-click the double line on the right, or click the chevron.

The area displays calculated values.

For example:

• The size of resistance in supports.
• Deflection and rotation in the place of the supports and loads.
• Maximum bending and torsion stress.
• Angle of twist.
• Mass of the shaft.

The following items are displayed in the Results pane:

Note: For more information on the calculated parameters, see the Engineer's Handbook chapters for shafts and beams.

The Load and Support lists include some of the important values at the position of every load and support. For a continuous load, the values are listed both for the beginning and for the end of the load.
