Structure Optimization Design Of Electric Needle Thin Linear Motor Of An Array Element

This thesis, which is based on the background of the National Natural Science Fund"knitting equipment of linear motor principle, control and thermal design research (Itemnumber50805109)", for multi-objective optimization algorithm,we use the array of textilemachinery in the power unit for ultra-thin needles which design as linear motor structure andoptimization of dynamic sub-section. The main thesis is to improve the traditional textilemachinery in the core components (needles) dynamic performance through dynamic analysisof electric power.and build knitting needles knitting needles slim linear motor theoreticalstructure models. On this basis, we also analysis the sub-part and a mover moving the supportand guide the design and optimization of the program structure of the stator part of theprocess, thereby improving the dynamic performance of the electric needle.First, the paper analysis the electric needles kinematics and dynamics analysis, knittingmachinery in the form of the basic requirements for electrical and magnetic structure of theneedles, and then the motor model establish a feasibility analysis, and ultimately get in lineelectric weave EA dynamics indicator needles slim linear motor design model structure andkey size.Secondly, in the context of determining the structure of electric needles Dynamic modelof permanent magnet synchronous linear motor, the stator magnetic field and the stability ofthe structure of the electrical part of the needles inside the stator part of the permanent magnetarray static analyzes, which laying the basis for design of the stator part, while design thepart of the promoter and determines the base glassfiber reinforced epoxy multilayer circuit board PCB design as a stator, in addition, to ensurethat the dynamic performance of electric needles achieving the targets of the program tosupport and guide the mover were part of the design.Finally, multi-objective optimization methods using constrained optimization while usingMatlab toolbox for electric needles mover part of the multi-objective optimization, andoptimization of the structure of the final results.In this paper, the work improve the dynamic power indicator needles knittingmachinery to meet the demanding requirements of the needles, knitting needles knittingmachines are widely used in the theoretical foundation for the next power-up.
