Abstract |
|
|
| Micro-electro-mechanical systems is that the size of component or the movement range is within micro grade, also called the
Micromechanical or Microsystems. It is a cross-curricular research field, covering topics such as physics, optics, mechanics, electricity,
biology and chemistry. The micro fluid system is an important branch of micro-electro-mechanical systems, it can be widely applied to
fields such as medical, chemical analysis and lubricating, etc.. Themicro pump is the actuating component of themicro fluid system. The
analytical modeling of the micro circular plate devices by electrostatic is problematic due to the complexity of the interactions between
the electrostatic coupling effect, residual stress and the nonlinear electrostatic force. Therefore, the dynamic behavior of the micro
circular plates is not easily analyzed using traditional analytic methods. Accordingly, this study develops an efficient computational
scheme in which the nonlinear governing equation of the coupled electrostatic force acting, residual stress and hydrostatic pressure
acting on the micro circular plates system is solved using a hybrid method (H.M.) which differential transformation with finite difference
approximation method. In addition, this study shows the dynamic behavior of the micro circular plates by a DC actuating load. |
