考虑流固耦合的压电微小泵的有限元运动分析

Finite Element Analysis of Mircopump with Fluid and Structure Interaction

采用ADINA对微泵进行有限元运动分析,在统一考虑结构与液体性质的基础上,研究压电泵在实际应用中激励力的频率、大小和液体密度、粘度对微小泵出口流量的影响,在此基础上,给出了在设计微泵时激励和传输液体的选择方法。

In the experiments, ADINA was used to structural and the fluid characteristics into consideration, carry on finite element analysis. Taking both the the influence factors such as frequency and magnitude of inspiritment, density and viscosity of liquid for the application of piezoelectricity micropumps were studied. Appropriate frequency of inspiritment and transmission liquid are chosen in the design of micropumps on the basis of those factors.
