摘要：
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.
