Defining Rotational Velocity To A Body In ANSYS® Mechanical(Illustrated Expression)

Defining Rotational Velocity As Tabular Data In ANSYS® Mechanical(Illustrated Expression)

We explained how to directly define rotational velocity in ANSYS® Mechanical. Definition of rotational velocity as tabular data in ANSYS® is very helpful to obtain rotational velocity that changes with time. In this article, we will explain how to define rotational velocity in ANSYS® Mechanical with tabular data.

How To Define Rotational Velocity As Tabular Data In ANSYS® Mechanical?

Click on ‘Rotational Velocity’ in ANSYS® Mechanical.

If you want to add rotational velocity to a part or component in ANSYS® Mechanical, click on the analysis tab shown by the red arrow above which is ‘Static Structural’ here, then click ‘Insert’ in the red box above. There will be a list opened, click on ‘Rotational Velocity’ as shown by the green arrow.

Parameters for rotational velocity in ANSYS®Mechanical.

To define rotational velocity to a component like above, you need to define the required parameters in that section above. You need to select geometry or body, definition method for rotational velocity such as ‘Vector’ or ‘Components’. All of these parameters are explained in this article. You can click and learn about them.

Select ‘Tabular(Time)’ for rotational velocity in ANSYS® Mechanical.

We defined all the parameters the same with the example given in the above article link. So if you want to define your rotational velocity as tabular data, click on the little arrow button as shown by the green arrow then select the ‘Tabular(Time)’ selection as shown by the red arrow above in ANSYS® Mechanical. So you can enter your changing values of rotational velocity with time from the table shown in the red box. You can fill that table or extend that table like in Excel.

Definition of rotational velocity from the table in ANSYS® Mechanical.

For example, we defined rotational velocity changing with time from the given table above. There is only 1 step, and this step is between 0-1 seconds. So you can only enter time values between 0 and 1. Otherwise, it will not be assigned in the analysis step. We entered our rotational velocities as shown above in ANSYS® Mechanical.

Conclusion

Simply, the definition of Rotational Velocity in ANSYS® Mechanical is very simple like above. Do not forget to leave your comments and questions about ‘Rotational Velocity’ as tabular data in ANSYS® Mechanical below!
