1、电磁驱动的片梭投射装置设计Electromagnetic Driven for Gripper Projection Device Design摘 要 当代物理学发展的极快，各种各样的装置都应运而生，在很大程度上提高了我们的生活质量的同时又节约了能源。这所有的一切跟我们人类的智慧分不开同时也是我们对物理学深入研究的必然结果。本项目研究对象为无梭织机中的片梭织机，探索的一种全新的引纬驱动原理，将是提高织机工作性能的有效方法，在其特有工艺原理基础上，提出电磁驱动的高速磁悬浮式引纬机理的设想，探讨磁悬浮式引纬器在高速往复运动中的动态特性及多物理场耦合机理，揭示磁悬浮式引纬原理进入高速织机引纬的可行性
2、，为片梭织机装备提供质量稳定可靠的通用引纬器。本课题研究电磁力驱动的磁悬浮式引纬原理，是利用“以电代机”省略中间机械传动(扭轴式储能驱动机构)环节，通过“零传动”驱动模式实现引纬器高速往复运动和无摩擦引纬。为了从原理上实现提速与降耗，同时满足现代织机高性能引纬器要求，将织机幅宽从 5.4m 增加至 8m、实际入纬率从 1200m/min 提升至2400m/min，因此无法忽略电磁投/制梭驱动理论、多物理场在动态运行中的相互耦合问题、磁悬浮式引纬的结构稳定性与运动稳定性等问题。本次毕业设计要求用本科四年所学的专业知识以及专业基础知识，为纺织机械的片梭设计“线圈感应型片梭投射装置” 。首先根据题目
