Vibration Research Of Shogging Motion Of The Guide Bar On High Speed Warp Knitting Machine

High speed warp knitting machine is the main quipment of the warp knitting industrialproduction, and high speed and high cut is an important research direction of the high speedwarp knitting machine.With production speed increase of the warp knitting machine, themechanical vibration and dynamics problem of cooperation and parts fit during knittingprocess are increasingly prominent. And stripping comb transverse institutions of strippingcomb, not only request that transverse time is short, acceleration is high and also accuracy ishigh, all these require stripping comb transverse vibration is small. This topic through theestablishment of warp knitting machine stripping comb transverse dynamic model and takesthe stripping comb as the main object analyses the warp knitting machine stripping combtransverse vibration are and sets up test research.The paper first introduces research situation of development about the warp knittingmachine mechanical and mechanical vibration, at the macro warp knitting machine strippingcomb of the transverse motion itself is a kind of vibration mode setting comb zero as thecenter, followed by stripping comb back and forth movement because of the special way, inthe stillness of the moment will also appear to rest position as the center of small amplitudevibration, mechanical vibration research mode reference to warp knitting machine strippingcomb of the transverse motion on the innovation of this paper is one of the point. Then thispaper expounds the warp knitting machine stripping comb transverse movement influencefactors, respectively from the mechanical and control into two aspects, in order to comb combitself as the base affect the transverse motion of the factors are eight aspects, especially thewarp knitting machine spindle speed is high or low is to comb comb transverse vibration sizeinfluence is the most obvious, transverse power device driver performance, connectiontransverse power plant and stripping comb member and the swing arm holding performance isthe most direct, motion curves and mat yarn group selection is through the warp knittingmachine control system for stripping comb the movement influence, warp knitting machine inthe outside environment is indirect influence factors. Again according to the structuraldynamics theory, the establishment of a stripping comb mathematical model, the applicationof Matlab Simulink simulation tool module to create the corresponding simulation model, soas to eliminate such as resonance, the damping and stiffness coefficient on the influence ofvibration theory and the practice question research provides a powerful tool and method.Finally builds vibration test platform on the stripping comb transverse carries on the actualanalysis, through the stripping comb vibration test experiment evaluate its anti vibrationproperties, test the correctness of the theory of vibration analysis, found that the vibration ofthe potential problems, for stripping comb dynamic optimization design to provide importantdata for analysis, and put forward the effective damping measures.In short, this topic has established single degree of freedom dynamic model about a kindof warp knitting machine stripping comb transverse, test and research the stripping combunder different conditions of vibration characteristics, provides certain ideas for optimizingthe design of stripping comb transverse motion.
