Weft-insert Carriers Movment Research Of Multiaxial Warp Knitting Machine

Multiaxial weft-insert carrier is the important component of multiaxial warp knitting machine,it works mainly according to the requirement of the warp knitting fabric.According to the different uses of the mulitiaxial warp knitting fabic,is also a variety of weft-insert technology.In this paper,mainly analysis the movement of weft-insert carrier,it can help to China to make mulitiaxial warp knitting machine,and provide a theoretical basis of controlling the production process to improve the the quality to multiaxial warp knitting fabric.This article introduced the construction of multiaxail warp knitting fabric as well as the production equipment,and analysized the application present situation and development trend of muliaxial warp knitting machine at home and abroad.Because the price of multiaxail warp knitting machine is very expensive and the manufacture technique is so difficulty,therefor,our multiaxial warp knitting machine by overseas import primarily.At present the research for multiaxail warp knitting machine is of great significance for speeding up the domestic warp knitting factory to produce the machines.This article first to analysis the warp knitting machine principle,then,the movement of weft-insert carrier which as a part of the machine is analyzed in depth,the best velocity of the mathematical model by motor-driven is obtained.As the weft-insert carrier's movement inacordance with the technique of multiaxial fabric,and this process is maily rely on motion control technology to achieve,so the movement control alogoruthms of weft-insert carrier and the control principles is also studied. Finally,this article studies the influence to the multiaxial fabric on the experimental analysis.It is conducive to the manufacturer in fabric weaving,to control adjustment weft-insert establishment and to enhance the fabric the quality.The multiaxial warp knitting fabric has the very big development space to in the industry of compound materials,our country will enlarge multiaxial warp knitting fabric application, therefore the analysis the movement to multiaxial weft-insert carries on the warp knitting machine is extremely important and it has the practical significance.
