Time Function Force Definition In ANSYS Mechanical(Illustrated Expression)

In this article of Mechanical Base, we will show how to define forces on parts or geometries in ANSYS Mechanical as time function. You can define forces that changes according to a time dependent function. So you can model the real physical model in ANSYS Mechanical. You know that the force is a boundry condition in finite element analysis(FEA). So definition of force propely is very important fact to obtain realistic and correct results.

How To Define Force That Is Time-Dependent Function in ANSYS Mechanical?

Click on force.

To assign a force as a function to your part in ANSYS Mechanical, you need to open the Mechanical interface. In this Mechanical interface, you need to right click to your analysis system(in this example, it is Static Structural) as shown above. Then you need to hover your Mouse at Insert as shown, then click on the Force as shown by blue box above in ANSYS Mechanical.

Click on a face of a feature in ANSYS Mechanical part

Select your feature in your part such as selected as a face as in this example above as shown by blue arrow. The geometry selection as done by Geometry tab in time-dependent force assignation that changes with time command as shown by red arrow. When you select the face to apply force, click apply in Geometry tab in ANSYS Mechanical.

Select the Function method for Force.

You can define force value to your geometry as Components and Vector. In this example, we selected Vectors to define our force as a function. Click om little pop-up menu as shown by red arrow above then click on Function method as shown in red box.

Define the function of force in ANSYS Mechanical.

Enter the function value of force as shown in red box above. You need to use “time” as a variable, the function will change as “time” changes. The result of the function in a table is shown with red arrow above in ANSYS Mechanical.

Select the direction of Force in ANSYS Mechanical.

Select the direction of force as shown by red box above, then click Apply as shown by red arrow above in ANSYS Mechanical.

Enter the Number Of Segments of Tabular Data.

Define the segmentation or row number of Tabular Data from the red box above. The result of the change is shown by red arrow. You can see the change.

Defined times and forces.

The time segmentation is defined by Number Of Segments section that shown in red box above. Also Force values are defines according to these times. The definition of forces as function of time values is very basic like above in ANSYS Mechanical.
