Simulating nonlinear vibration in MEMS devices

Inertial MEMS — gyroscopes and accelerometers — and MEMS timing devices are built around vibrating structures operating at high Q, where the vibration behaviour is what determines whether the device works.

The nonlinear effects on that vibration are hard to model. The usual route is lumped models that need significant pre-work and assumptions, and return an approximate answer — so problems that only surface in fabrication are missed when they could have been avoided.

Quanscient Allsolve changes that. Harmonic balance is the enabler: it makes realistically large nonlinear vibration problems solvable, including modal coupling and the stiffening and softening that comes with it.

On top of that, surrogate models let you explore the design space quickly and cost-effectively, even on very large problems.
