【摘要】 利用聚酰亚胺(PI)优良的机械、绝缘、耐热等性能,设计出基于PI膜的磁控光开关.给出合理的线圈宽度与间隙宽度,提出了八边形的线圈绕组结构,计算得出PI膜悬臂梁光开关驱动电压与工作距离的关系,并对悬臂梁长度、宽度、厚度进行优化.在驱动电压为2V时,自由端位移达到2mm.更多还原

【Abstract】 A kind of electromagnetic actuation optical switch is designed based on the high performance of polyimide (PI) in mechanical character, insulation and heat-resistant . We analyzed the winding configuration and chose the regular octagon form and also studied the relationship between the driving voltage and working distance about the PI-cantilever, which aimed at optimizing the structure of the PI-cantilever in length, width and thickness. At a driving voltage of 2V, the movable part got a displacement of 2 mm.更多还原
