How Do You Make a Dynamic Spring in SolidWorks?

In this tutorial, we will learn how to create a dynamic spring in SolidWorks. Springs are widely used in mechanical designs and understanding how to create and manipulate them is essential for any SolidWorks user.

Creating the Base Geometry

To start, open a new part file in SolidWorks. We will begin by creating the base geometry of our spring.

Step 1: Go to the “Sketch” tab and select “Top Plane” from the feature tree. Click on “Sketch” to create a new sketch on this plane.

Step 2: Use the sketch tools such as lines, arcs, and circles to draw the profile of your spring. You can make it as simple or complex as you like, but keep in mind that complex shapes may require more advanced techniques.

Step 3: Once you have finished creating your sketch, exit the sketch mode by clicking on “Exit Sketch” or pressing Esc on your keyboard.

Creating the Helix

In order to make our spring dynamic, we need to create a helix that will define its shape. Follow these steps:

Step 1: Go to the “Features” tab and click on “Helix/Spiral”.

  • Note: If you don’t see this option, go to “Tools” > “Add-Ins” and enable the “Spiral/Helix” tool.

Step 2: In the Helix/Spiral PropertyManager, specify the following parameters:

  • Diameter: The diameter of your spring
  • Pitch: The distance between each coil
  • Height: The overall height of your spring
  • Revolution: The number of revolutions your helix should make

Step 3: Click “OK” to create the helix. You will see a preview of the helix on your screen.

Creating the Sweep

Now that we have our base geometry and helix, we can create the sweep feature to give our spring its shape.

Step 1: Go to the “Features” tab and click on “Sweep”.

Step 2: In the Sweep PropertyManager, select the following options:

  • Select Profile: Choose the sketch you created in the first step.
  • Select Path: Choose the helix you created in the previous section.

Step 3: Click “OK” to create the sweep. Your spring will now take shape based on the profile and helix you defined.

Making the Spring Dynamic

To make our spring dynamic, we will use SolidWorks’ Flex feature. This allows us to manipulate our spring’s parameters and see it adjust in real-time.

Step 1: Go to the “Evaluate” tab and click on “Flex”.

Step 2: In the Flex PropertyManager, select “Dynamic” from the Type dropdown menu.

Step 3: Adjust any of the available parameters such as pitch, diameter, or height to see your spring change shape accordingly.

Conclusion

Congratulations! You have successfully created a dynamic spring in SolidWorks. By following these steps, you can now design and manipulate springs to fit your specific mechanical design needs.

Remember to experiment with different shapes and parameters to explore the full capabilities of SolidWorks’ spring features. Have fun designing!
