Maglev Drive Dynamic Analysis And The Knitting Needle Knitting Jacquard Circle Machine Structure Design

Based on the combination of traditional computer jacquard knitting needle selectionprinciple and basis of the theory of electromagnetic and permanent magnet，put forward theprinciple and method of electromagnetic-permanent magnet hybrid driving knitting,throughthe theoretical analysis of magnetic suspension type designdriving knitting needle devicebasic mechanism.By establishing the physical model of electromagnetic-permanent magnetdriven knitting needle so as to solve the electromagnetic driving force thatthe mechanicsanalysis data by provide theory for suspension driven knitting needle.In turn the basis fordynamic analysis driven knitting needle, reasonable research new maglev type computerjacquard needle selection structure design, component design, the whole machine design.In this paper, focusing on traditional knitting needle"three-function digital" jacquardmotion trajectory analysis as the basis, the maglev driver stressanalysis and structuredesigning, knitting needle mechanical analysis and dynamic research, study the influence ofyarn tension and performance and magnetic suspension type knitting jacquard circle machinestructure design researching, discussion and analysis. One mechanical model of the traditionalknitted jacquard circle machine key needle selection principle and design method providetoknitting needle.In this paper, the concept of "inversion method" was used to design the maglev knittingjacquard circle machine. On the basis of traditional knitted jacquard circle machine, using thefinite element method for magnetic levitation driven knitting needle dynamic analysis.wedesigned the working principle and structure for5-inches multi-array magnetic levitationknitted jacquard circular knitting machine through simulation form, and verified that thedesign meets the technical requirements of knitted computer jacquard knitting machinethrough real-time animation. Therefore, this subject will be presented by means of magneticlevitation theory and technology, with "electric generation machine" thinking to replace the mechanical needle selection mode of traditional knitting needle jacquard circular machine,achieved needle selection principle of no friction, high efficiency, and high-frequencydesign.
