Performing a Buckling Analysis on a Cyclone Separator Stand Using SolidWorks

Buckling analysis is an essential aspect of structural analysis, especially for slender components subjected to compressive forces. In this blog, part of the CAE Simulation using SolidWorks series, we’ll walk through the process of setting up and running a buckling analysis for a cyclone separator stand. This guide is perfect for beginners and professionals alike, offering step-by-step insights into SolidWorks simulation best practices. 

Getting Started: Setting Up the Model 

To begin, open SolidWorks and import the model of the cyclone separator. Since our focus is on the stand, we’ll exclude the cyclone separator from the analysis. 

Suppress the Cyclone Separator: 

• Right-click on the cyclone separator parts and select Exclude from Analysis. 
• This ensures that only the stand remains for the buckling analysis. 

Create a New Study: 

• Go to Simulation > New Study and select Buckling Analysis. 
• Rename the study for clarity and click OK. 

Defining Material Properties and Boundary Conditions 

Accurate material properties and boundary conditions are crucial for any CAE simulation course. 

Apply Material: 

• Right-click on the stand and select Apply Material. 
• Choose Alloy Steel as the default material. 

Set Fixtures: 

• Since the stand is fixed to the ground, right-click and choose Insert Fixed Geometry. 
• Select the base faces of the stand to define the fixed boundary condition. 

Applying the Load 

The next step is to define the external forces acting on the stand. 

Define the Load: 

• Right-click on External Loads and select Force. 
• Apply a compressive load of 150 kN on the designated face of the stand. 
• Click OK to confirm. 

Meshing the Model 

Mesh quality directly impacts the accuracy of the results in SolidWorks CAE simulation. 

Create the Mesh: 

• Right-click on Mesh and select Create Mesh. 
• Use a fine mesh for better precision. 
• Inspect the mesh to ensure proper discretization of the geometry. 

Running the Simulation 

Once the setup is complete, it’s time to run the simulation and analyze the results. 

Run the Simulation: 

Click on Run Study to begin the simulation. 

Analyze the Results: 

• After completion, view the Resultant Amplitude Plot. 
• Right-click on the result and select Animate to visualize how the stand might fail due to buckling. 

Understanding the Buckling Factor of Safety 

The buckling factor of safety is a critical metric in structural analysis. 

View the Buckling Factor of Safety: 

• Right-click on the result and choose List Buckling Factor of Safety. 
• For this analysis, the factor of safety was approximately 10. 

Interpretation: 

A buckling factor of safety of 10 means the structure can withstand 10 times the applied load before failing due to buckling. 

For most designs, a factor of safety above 3 is considered safe. 

Enhancing the Design 

Buckling resistance can often be improved by adding stiffeners to the structure. 

Effect of Stiffeners: 

• Adding stiffeners at the midsection or corners increases the structural stability. 
• For the same applied load, the buckling factor of safety will increase, making the design safer. 

Try It Yourself: 

Experiment with adding stiffeners and observe the changes in the buckling factor of safety.
