Dynamic Characteristics of a Novel PDMS Electromagnetic Microvalve
摘要
Abstract
A novel PDMS electromagnetic microvalve which can be used in the pneumatic pressure control for labon-a-chip applications is presented.The structure and the working principle of the pneumatic electromagnetic microvalve are introduced.The mathematical models of the electromagnetic actuator are given,and the simulation models of the self-inductance coefficient,the coil current,the motion voltage,the mechanical motion,and the electromagnetic force are researched.The multi-physical field coupling mathematical models of the electromagnetic force,the elastic deformation force of the valve-membrane,the flow force of gas and liquid in pneumatic microchannels are developed.The deformable model of the valve-membrane,the outlet flow rate model of the PDMS electromagnetic microvalve,and the five sub models of the electromagnetic actuator are given by the software MATLAB/ Simulink.The simulation of the dynamic response of the electromagnetic actuator and the dynamic flow rate of the PDMS electromagnetic microvalve is carried out.The predicted characteristics of the valve-spool driving force,the valve-spool response time,and the dynamic flow rate of the PDMS electromagnetic microvalve are given.关键词
