Automating Processes in Ansys Mechanical with the Object Generator

1. Introduction

Welcome to another tech tip video on Ansys Mechanical! In this video, we will be focusing on how to use the Object Generator to automate processes such as creating joints and applying loads on repeated members.

2. Understanding the Object Generator

The Object Generator in Ansys Mechanical allows us to automate repetitive tasks by creating name selections or groups. These groups can be used to select specific surfaces or components for further actions.

3. Creating Name Selections in Spaceclaim

To begin automating processes, we first need to create name selections in Spaceclaim. These name selections will help us identify and select the surfaces we want to work with. By utilizing the selection capabilities of Spaceclaim, we can quickly create name selections for top and bottom vertexes, bolts, and washers.

4. Importing Name Selections to Ansys Mechanical

Once we have created the name selections in Spaceclaim, we can easily import them into Ansys Mechanical. This allows us to utilize the name selections for further actions within the software.

5. Creating Name Selections in Ansys Mechanical

Alternatively, we can also create name selections directly within Ansys Mechanical. By selecting the desired vertexes or surfaces, we can create name selections to be used in subsequent steps.

6. Inserting Joints for Bolt Assemblies

In order to connect the bolts to the washers, we need to insert joints. With the help of smart selection in Ansys Mechanical, we can easily select the surfaces we want to work with. This feature eliminates the need for manual filtering and selection, making the process more efficient.

7. Automating the Process with the Object Generator

The Object Generator comes into play when we want to automate the process of inserting joints for multiple bolt assemblies. By selecting the desired features and using the Object Generator, we can duplicate and automate the process for all the assemblies at once.

8. Applying Bolt Pretension

After setting up the joints, it's time to apply bolt pretension. This step ensures proper load distribution and accuracy in the analysis. By selecting the bolts and setting the desired clamp load, we can easily apply bolt pretension to all the line bodies.

9. Setting Up Bolt Pretension for Top Bolt

To specifically set up bolt pretension for the top bolt, we utilize the name selections created earlier. This allows us to target only the top surfaces of the bolts and apply the desired pretension.

10. Setting Up Bolt Pretension for Bottom Bolt

Similar to the top bolt, we can also set up bolt pretension for the bottom bolt using the name selections. This ensures accurate analysis and load distribution across the entire assembly.

11. Conclusion

In conclusion, the Object Generator in Ansys Mechanical is a powerful tool that allows engineers to automate repetitive processes such as creating joints and applying loads. By utilizing name selections and smart selection, we can streamline the analysis workflow and save valuable time.
