SOLIDWORKS Simulation – Snap Fit Design and Optimization
Summary
Snap-fits are used now-a-days everywhere from remote controllers to pen caps and have many variations including cantilever, annular, and torsional snaps. They can be used to increase assembly speed and have the added benefit of less loose parts. There are some industry accepted equations available online that can help with ball-park dimensioning, but my personal favorite approach is to use SOLIDWORKS Simulation to run a linear static study since this is best practice before running a nonlinear static study anyway. I decided on a cantilever snap, one of the more common snap-fits, but whichever type of snap you decide on I recommend starting with a coarse mesh for fast solving times to narrow down the rough design – fail fast and fail frugal.
