摘要：

减少电脑横机在编织过程中的发热、振动和断针,提出一种利用电磁铁阵列驱动永磁体织针的非接触式的织针驱动方法,同时设计了织针与驱动分离的新型磁驱动横机结构。通过将电磁铁阵列中的铁芯、永磁、气隙等元素等效为磁阻和磁势,建立了电磁阵列驱动永磁织针的等效磁路模型,分析了电磁铁阵列在水平往复移动时的等效磁路模型的磁通量,推导出永磁织针在电磁铁阵列不同位移条件下的磁力模型,计算织针在不同条件下的受力数值,并利用Maxwell电磁仿真软件对磁驱动模型进行了仿真。结果表明:将等磁路模型和仿真模型的数据进行了比对和分析,验证了电磁铁阵列式的织针磁驱动等效磁路模型的正确性。

Abstract:

In order to reduce heat, vibration and needle breakage during knitting process of computerized flat knitting machine, a non-contact needles driving method that permanent magnet knitting needles were driven by electromagnet array was proposed. At the same time, a new type of magnetic drive flat knitting machine structure with separate needle and drive was designed. By equivalent the elements of iron core, permanent magnet and air gap in the electromagnet array to magnetoresistance and magnetic potential, the equivalent magnetic circuit model of permanent magnet knitting needle driven by electromagnetic array was established. Then, by analyzing the flux of the equivalent magnetic circuit model of the electromagnet array moving horizontally to and fro, the magnetic force model of the permanent magnet knitting needle under different displacements of the electromagnet array was deduced. Thus, the force values of knitting needles under different conditions can be calculated. Maxwell electromagnetic simulation software was adopted to simulate the magnetic drive model, the data of the equivalent magnetic circuit model and the simulation model were compared and analyzed, and the validity of the equivalent magnetic circuit model was verified.

Key words: flat knitting machine, permanent magnetic needle, electromagnetic driving, magnetic equivalent circuit method, Maxwell simulation
