Optimization of flexible watch components with ANSYS/LS-Dyna, ANSYS Workbench and optiSLang

Watch industry mechanisms involve a large number of high precision flexible pre-constrained mechanical components. Using traditional prototyping, the definition of non-deformed geometries for production is a costly manual iterative process. The use of non-linear finite elements modeling improves this process and the coupling of the finite elements codes to a stochastic optimization toolbox like optiSLang makes it automatic and more robust.
