Simulation tool for complex-engineered micro-optical electromechanical system
In order to improve the design and analysis ability of complex microsystems with multi-physical domain coupling
an efficient design and modeling method based on system-level structure was presented. In comparison
it was difficult to simulate such kind of microsystem using conventional modeling tools. Such tools were either based on distributed-element analysis
which was time-consuming and too computationally intensive for complex systems
or based on traditional lumped-element analysis
which was limited by an inability to handle algebraic constraints in general. For design
a novel graphical user interface (GUI) was presented. It allowed users to quickly configure complex systems in 3D using a computer mouse or pen at a faster rate than it might be drawn with pencil and paper. The GUI was coupled to a novel and powerful netlist language for design flexibility. For modeling
recent advances in analytical system dynamics and differential-algebraic equations (DAEs) were applied into a framework that facilitates the systematic modeling of multidisciplinary systems that may comprise static or dynamic constraints. For a test case
a complex microsystem fabricated by Sandia National Laboratory (SNL) was efficiently modeled and simulated. This micro optics electro mechanical system comprises mirrors
gears
hinges
a slider
electronic components
comb drives
and electromechanical flexures. The results prove the effectiveness of the method
which presents the netlist language and modeling methodology are beneficial to configure and simulate one of the most complex-engineered micro systems to date.
