基于一种具有双向形状记忆功能的光致弯曲材料,设计了新型有阀微泵结构并制作了样机。结合材料的光致弯曲效应等效理论,采用ANSYS软件建立了微泵空腔结构的几何模型,并对所建模型的泵水体积进行了计算求解。对样机进行实验得到了微泵的实际泵水性能,将其与理论计算结果进行对比,得出两者基本一致的结论,从而验证了微泵结构设计的合理性。光致弯曲材料在微泵上的应用形式,对相关工程应用有一定的参考价值,光致效应的等效也为解决相关问题提供了研究方法。
Based on a photo-induced bending material which has two-way shape memory function,a novel micro-pump with valves was designed and made.Combined with material deformation principle,the micro-pump＇s finite element model was built by using the finite element software ANSYS,and the pumping capacity calculated by ANSYS was gained and compared with the one came from the pump prototype＇s experimental results,then the consistency of which validates this micro-pump design＇s rationality.The material application on micro-pump has some reference values for relative engineering application and the photo-induced bending effect equivalent also provides research methods for similar problems.
