Asset Overview

If you understand the working principle of the [Swiss lever escapement](https://skfb.ly/LIwX) and if you are familiar with [flexures](https://skfb.ly/OtOU), understanding this design should be straightforward. *(If not, you can click on the links and have a look at the 3D models.)* In a way, anyone who ever played with a metal ruler (bending it) already knows enough about flexure beams to understand what is going on in this *Zenith Defy Lab* system. However, it is necessary to make use of [Finite Element Analysis](https://en.wikipedia.org/wiki/Finite_element_method) to develop and validate this type of design. --- This model was reconstructed from illustrations found on the Internet (*). Using the CAD model of the monolithic silicon part, I performed FEM simulations with SolidWorks Simulations. Then, I exported the WRL deformed models and pursued the work in Blender (using shape keys). *\*) This 2D drawing was particularly helpful.* ![](http://c.yamahata.fr/sketchfab/Defy_Lab_oscillator-drawing.jpg)
