【摘要】：传统针织装备在编织过程中采用机械式选针原理,选针机构与编织机构因机械动作而产生冲击与摩擦,因而在现有机械式选针方式中进一步提高针织圆纬机效率将受到限制。本文提出一种磁悬浮驱动织针原理模式,实现“以电代机”的“零传动”织针模式,从工艺原理上消除了机械结构中的刚性接触、冲击、摩擦等影响。本文研究是在国家自然科学基金项目(51305309)的资助下,基于以磁悬浮式驱动针织原理基础上,针对针织圆纬机关键技术展开研究,其重点研究内容有:分析驱动织针受力模型,建立电磁驱动磁力模型,通过数值计算与实验测量验证了理论推导的有效性;建立线圈结构与磁力耦合关系模型,分析和求解不同驱动结构下磁力分布规律;通过遗传算法,结合蒙特卡罗方法优化驱动尺寸与结构,由数值计算与有限元计算比较验证优化后的驱动结构的合理性;使用高导磁筒壁束缚驱动组件磁场,解决驱动组件间磁场相互耦合问题,通过对磁路分析说明了高导磁筒壁的作用机理,分析了高导磁筒壁对磁力分布的影响,并提出解决方案,通过有限元仿真验证了解决方案的可行性。本文搭建了高速磁悬浮驱动织针实验平台及实验样机,通过实验样机调试其结果证明磁悬浮驱动织针原理、理论分析及设计方法符合针织圆机性能要求,为进一步开展磁悬浮驱动针织圆机实用化提供技术支持。
[Abstract]:The traditional knitting equipment adopts the principle of mechanical needle selection in the process of knitting. The needle selecting mechanism and knitting mechanism produce impact and friction because of mechanical action, so it will be limited to further improve the efficiency of knitting circular weft knitting machine in the existing mechanical needle selection mode. In this paper, a principle mode of magnetic levitation driven needle weaving is presented, which realizes the "zero drive" needle mode of "electric replacement machine", which eliminates the influence of rigid contact, impact and friction in mechanical structure from the principle of technology. Based on the principle of maglev driven knitting and supported by the National Natural Science Foundation of China (51305309), the key technology of circular knitting machine is studied in this paper. The main research contents are as follows: analyzing the force model of driving knitting needle, The electromagnetic driving magnetic force model is established, and the validity of the theoretical derivation is verified by numerical calculation and experimental measurement. The coupling model of coil structure and magnetic force is established, and the distribution of magnetic force under different driving structures is analyzed and solved. Through genetic algorithm and Monte Carlo method to optimize the drive size and structure, numerical calculation and finite element calculation are compared to verify the rationality of the optimized drive structure. The magnetic field of the high magnetic cylinder wall is used to solve the problem of magnetic field coupling between the driving components. Through the analysis of magnetic circuit, the mechanism of the high magnetic conductivity cylinder wall is explained, and the influence of the high magnetic tube wall on the magnetic force distribution is analyzed. The feasibility of the solution is verified by finite element simulation. In this paper, the experimental platform and prototype of high speed maglev driven knitting needle are built. The results of debugging the experimental prototype prove that the principle, theoretical analysis and design method of magnetic levitation drive needle can meet the performance requirements of circular knitting machine. It provides technical support for further practical application of maglev driven circular knitting machine.
