为提升多物理域耦合的复杂微光机系统设计分析能力,提出了高效的基于系统级构架的设计和建模方法。而使用传统的建模工具在模拟这样的微系统时存在困难,这些工具或是基于分散的单元分析,计算较复杂费时;或基于传统集总单元分析,不易处理代数约束条件。对于系统设计,建立易用的图形用户界面(GUI),允许设计者立体、快速的配置复杂系统。创立功能丰富的网表语言,并将模型与之结合来满足设计的灵活性。应用系统动力学理论,通过能量方程、约束和载荷来表示复杂的、多学科的组件,建立和求解微分代数方程。对桑迪亚国家实验室制作的一个复杂微光机系统进行了有效的建模和计算,系统包括微镜片、齿轮、铰链、滑块、电子元器件、梳状驱动器和挠性梁。结果显示了方法的有效性,说明该方法有利于模拟微光机这样多学科的、含有静态和动态约束的系统。
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.
