摘要

研究了柔性膜内磁性微粒的设计与优化,以及影响柔性膜性能的因素。在这项工作中,镍(Ni)被用作磁性颗粒,聚二甲基硅氧烷(PDMS)被用作膜材料,被认为是柔性膜的基质成分。利用Comsol Multiphysics 4.2软件模拟了不同粒径、不同排列方式和不同间距的Ni粒子。因此,大挠度磁颗粒嵌入膜的最佳设计是采用圆形膜,微磁颗粒密度低,呈平面分布。初步的仿真结果与理论计算结果进行了比较,验证了分析的正确性。

Design and optimization of magnetic particles embedded in PDMS membrane
A design and optimization of the magnetic particles embedded inside a flexible membrane and factors contributing to the membrane performance have been studied. In this work, Nickel (Ni) is used as magnetic particles and Polydimethylsiloxane (PDMS) is used for membrane material which is considered a matrix component of the flexible membrane. Ni particles with various particle sizes, arrangement and spaces between Ni particles are simulated by using Comsol Multiphysics 4.2. As a result, the optimum design of magnetic particles embedded in membrane for large deflection is by having circular shape membrane with low density of tiny magnetic particles in planar distribution. A preliminary simulation result has been also compared with the theoretical calculation to validate the analysis.
