中文摘要：

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.

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 warp- knitting machine which run at the speed of 1 000 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 shngging was testified validly.
