Resonator Design

Resonators are commonly used in a wide variety of MEMS and other devices. They take advantage of the interaction between inertia and stiffness to provide large motions with little energy input.

However this coupling of inertia and stiffness makes designing them challenging. This is where simulation can greatly aid in the development process.

Basic resonator design

Basic resonator design involve static, modal and harmonic analysis. This fully characterize the mechanical behavior of resonators and allows engineers to truly understand the dynamic effects of their design decisions.

Resonators need to be efficient, impart large motions but also durable. These conflicting requirement means they need to be carefully designed and analyzed using multiple simulation methods.

Resonator Optimization

Resonator design is a challenging problem. With parametric optimization, it is possible to fully characterize these devices within a given design space.

The data provided by an optimization study is invaluable to understanding the limits of the design, finding the optimal trade-off and reducing product development time.

Actuation

Typically resonators are actuated using magnetic or electrostatic forces. Accurate characterization of position vs force is essential in the development of efficient control systems for actuators.

We even offer solutions to link up reduced order models for the structure and the actuators to provide realistic plant models for control system design.
