Defining A Moment As A Function In ANSYS® Mechanical(Illustrated Expression)

2 min reading time..

In this article of Mechanical Base, we will show you how to define time-dependent Moments in ANSYS® Mechanical. So you can define Moment value to geometries as time-dependent functions that provide to obtain the very realistic model of physical systems in ANSYS® Mechanical. Moments are boundary conditions in finite element analysis(FEA) that is very important to define correctly.

You can also find out lots of informative content in Mechanical Base about ANSYS®, like this article to learn ANSYS® completely.

How To Define Time-Dependent Moment Value In ANSYS® Mechanical?

Click on Moment.

To apply a moment as time function to a part in ANSYS® Mechanical, you need to right-click on the analysis system(Static Structural in this example). After that, you need to hover your mouse on the Insert tab as shown by the red arrow then click on the Moment command as shown in the red box above in ANSYS® Mechanical.

Select the geometry in ANSYS® Mechanical.

You can select the geometry to apply the moment as time function on it as shown by the red arrow above. Click on the geometric feature or features then click on the Apply button in the Geometry section as shown by the red arrow in ANSYS® Mechanical.

Select the Function method for time-dependent Moment in ANSYS® Mechanical.

You can define the moment value as Components or Vector but we will select Vector from Define By section above for this example. Click on the little-pop-up menu as shown by the red arrow above then click on the Function method to define a time-dependent moment in ANSYS® Mechanical.

Define the function of Moment.

Define the moment function as shown in the red box above. Use “time” as a variable when you are typing the function. You can see the result of the function with changing time from Tabular Data as shown by the red arrow above.

Change the direction of time-dependent moment.

You can define the direction of the time-dependent moment in ANSYS® Mechanical as shown by the red box above. Then click the Apply button from the Direction section as shown by the red arrow.

Select the time-dependent moment behavior.

Mechanical as; Rigid, Deformable, Coupled, Beam, etc… as shown by the red box above.

Change the Number Of Segments value of time-dependent moment in ANSYS® Mechanical.

You can change the segmentation of Tabular Data as shown by the red arrow above by entering several Segments values as in the red box. This will change the dividing value of 0-1 seconds in Tabular Data also which defines the row number of Tabular Data.

Conclusion

So defining time-dependent moment value in ANSYS® Mechanical is very easy.
