Solidworks model for a parametric stacked wave spring.

I couldn't find a satisfactory wave spring model in Solidworks, so I made my own. It will be used in a future design. In theory it should work for extension & compression; my application requires compression.

16 Sep 18: Added more variables.

There are three main objects here: the wave, the top & the bottom "washers". The wave geometry is governed by the WaveOD, WaveID, & SectionHeight.

Each wave has 4 top & bottom contacts.

Now the top & bottom "washers" can be manipulated separately from the wave geometry.

Here are the configurable variables:

• WaveOD
• WaveID
• BottomOD
• BottomID
• BottomHeight: or thickness of just the bottom "washer"
• TopOD
• TopID
• TopHeight
• Overlap: how much each wave will merge with its neighbors for strength, at the cost of reduced spring action
• SectionHeight
• TotalHeight
• NumWaves: number of desired waves making up the stack. Must be greater than 3.

The cross-section is a rectangle with SectionHeight as its height, and (WaveOD-WaveID)/2 as its width.

We'll have to see how well this actually prints or functions.

I have not tested it yet.
