Defining Acceleration in ANSYS Mechanical

In this article of Mechanicalland, we will show you how to define an acceleration value to a body in ANSYS Mechanical. In physical systems, acceleration is a very important parameter to find out or solve this physical system. Also in engineering systems, designers use acceleration parameters to define another engineering parameter in an engineering problem. So, in finite element analysis of a physical or engineering system, acceleration is a boundary condition. Also, to solve a physical or engineering problem, the definition of acceleration in the correct way is a very important thing. Moreover, you will see a defining acceleration in ANSYS Mechanical is very simple.

You will learn how to define acceleration value to a body in ANSYS Mechanical at the end of this text.

How to Define an Acceleration Value to Bodies in ANSYS Mechanical?

Firstly, to define an acceleration value, you need to open the ANSYS Mechanical interface by double-clicking on the Model tab in ANSYS Workbench. Right-click on the analysis system in ANSYS Mechanical(Static Structural in this example). Hover your Mouse on the Insert tab as shown by the blue arrow above then click on the Acceleration as shown by the blue box.

Secondly, as you can see from above, we can apply acceleration only to All Bodies in ANSYS Mechanical as shown blue box. Also, you can define your acceleration value as Components or Vector. After that, to define the acceleration value as a component, you need to enter the whole acceleration values in the X, Y, and Z axes. If you define your acceleration value as Vector, you need to select a vector for the direction of acceleration and you need to enter an acceleration value again in ANSYS Mechanical.

Define the Body that Accelerates

Finally, in this example, we define our acceleration value as components. So, we entered our acceleration values to X, Y and Z coordinates as 5, 10, and 15 m/s^2 values respectively as shown in the red box above. Also, you see the result of acceleration in the shape of a yellow arrow as shown by the red arrow. Defining acceleration in ANSYS is very simple like this.

ANSYS provides very good tools to obtain very good FEA analyses and simulations. Check the other tools of ANSYS that you can use when you are building your FEA analyses.
