Design of Flexible Electronic Shogging System for High-Speed Warp-Knitting Machine

A flexible electronic shogging system was presented based on rotary type servo motor,which aimed to improve the dynamic response of the shogging drive and decrease the impact of the guide bar during the higher speed running of warp-knitting machine.In this system,the speed control mode,faster response servo motor,no-flat modified trapezoid motion law,and its electronic cam were chosen;the realization standard and method were also introduced in details.The speed response curves of loaded motor indicated that the system could satisfy the technology requirements of high-speed warpknitting machine which run at the speed of 1000 r/min in the experiments,and the vibration curves showed that the guide bar had weaker mechanical impact and higher dynamic response characteristics.The results indicated that the flexible electronic shogging system designed following the previous step was successful,and the design principle of the electronic shogging was testified validly.

以正好满足产品需求为约束条件的车间最优生产计划

研究以正好满足产品需求为约束条件的预选性自动化车间（FAW)伯最优生产计划问题，首先根据实际需要建立车间生产计划的含需求约束的非线性规划模型，然后为求解方便通过引进约束将其转化成线性规划模型，由于这种模型对于一般车间来讲其规模已经很大，很难在微机上用单纯形法在可接受的时间内获得其最优解，为此，提出分别用卡马卡算法和基于卡马卡算法的关联预测法来求解车间最优生产计划问题，并编制了相应软件，最后，通过算例研究，比较了卡马卡算法，基于卡马卡算法的关联预测法和Ｍatlab中的线性规划法，结果表明所提方法非常适合将ＥＲＰ／ＭＲＰＩＩ下达给ＦＡＷ的中期计划最优分解成由ＦＡＷ中各ＦＭＳ执行的短期计划。
