摘要

Lumped-constant simulation of microelectromechanical systems (MEMS) is performed by solving numerically systems of coupled ordinary differential equations expressing Kirchhoff's laws and those of classical mechanics. One of the challenges is to describe mathematically the dynamics of these systems in a form that is both numerically stable and computationally efficient. The goal of this paper is to show that the representation of rigid-body dynamics based on the Euler parameters satisfies these requirements: it can describe arbitrary three-dimensional motion, its numerical stability properties are superior to those of other more frequently used parametrizations, and it can be implemented in a simulator in an efficient manner using so-called element stamps.
