查询词典 CAD

Micro-scale effect and multi-field coupling are characteristics of the design of micro-electro-mechanical system. However, the current macroscopic structure-oriented CAD systems have not been able to meet the increasing requirements for the design in micrometer scale. Therefore, a flexible design modeling methodology for MEMS based on Petri net is put forward.

微机电系统设计具有微尺度效应和多物理场耦合的特点，而现有的面向产品宏观结构的CAD系统难以满足微米尺度设计需求，为此提出一种基于Petri网的MEMS柔性设计建模方法。
