How Do You Force Analysis in SolidWorks?

When working with SolidWorks, there may be instances where you need to force analysis to ensure the stability and reliability of your designs. Force analysis allows you to understand how different forces and loads will affect your model, enabling you to make necessary adjustments and improvements. In this tutorial, we will explore how to perform force analysis in SolidWorks.

Step 1: Open the Assembly

To start, open the assembly file in SolidWorks that you want to analyze. It is essential to have a completed assembly before proceeding with force analysis.

Step 2: Define the Forces

Once your assembly is open, it’s time to define the forces that will act on your model. SolidWorks provides several tools for defining forces, including:

  • Force: Represents a specific force acting on a particular component or part of the assembly.
  • Torque: Represents rotational forces acting on components.
  • Gravity: Represents the gravitational force acting on the entire assembly or specific components.

To define these forces, navigate to the “Evaluate” tab in the SolidWorks menu and click on “Force Analysis.”

Step 3: Apply Constraints

In order to accurately simulate real-world conditions, it’s important to apply constraints that mimic how your assembly will be fixed or supported in its actual environment. Constraints can include fixed supports, hinges, sliders, and more.

To apply constraints, navigate to the “Evaluate” tab in the SolidWorks menu and click on “Constraints.”

Step 4: Set Up Material Properties

In order for SolidWorks to accurately calculate stress and deformation values during force analysis, it’s crucial to assign appropriate material properties to your components. This includes defining the material type, density, and other relevant properties.

To set up material properties, navigate to the “Evaluate” tab in the SolidWorks menu and click on “Material.”

Step 5: Run the Analysis

With all the necessary parameters defined, it’s time to run the force analysis in SolidWorks. Click on the “Run Analysis” button located on the “Evaluate” tab.

During the analysis, SolidWorks will calculate stress and deformation values based on the forces applied and constraints defined. The results will be displayed in graphical form, allowing you to visualize areas of high stress or deformation.

Tips for Interpreting Results

  • Stress: Areas with high stress values may indicate potential failure points. Consider reinforcing these areas or adjusting your design accordingly.
  • Deformation: Excessive deformation can lead to misalignment or interference issues.

    Identify areas of significant deformation and make necessary modifications.

  • Safety Factor: SolidWorks calculates a safety factor for each component based on applied forces and allowable stress limits. A higher safety factor indicates a more robust design.


In conclusion, force analysis is a crucial step in ensuring the structural integrity of your designs in SolidWorks. By defining forces, applying constraints, setting up material properties, and running analyses, you can identify potential weaknesses or areas for improvement before moving forward with production. Remember to interpret the results carefully and make necessary adjustments to create a robust final design.
