SM8-TOP2无缝内衣圆机织针的运动参数分析

SM8-TOP2型无缝内衣圆机为实现多种花色组织的设计创造了条件，但在组织设计时存在着优化设计问题。为此，在系统研究SM8-TOP2无缝内衣圆机成圈系统设置和分析常用组织成圈原理的基础上，采用MatLab对成圈、集圈和添纱组织的织针运动轨迹、速度和加速度的变化趋势进行研究。结果表明：SM8-TOP2无缝内衣圆机可通过控制三角、选针设置和穿纱方式等多种手段实现花型设计；在成圈过程中，织针运动平稳，加速度的最大值出现在压针成圈阶段，有利于新线圈的形成。

Analyzing needle track of SM8-TOP2 seamless-wear circular knitting machine

SM8-TOP2 seamless-wear circular knitting machine creates conditions for designing many varieties of patterns. However, it can be optimized when designing. Therefore, we studied the settings of SM8-TOP2 electronic seamless-wear circular knitting machine, analyzed the loop forming principle of common stitches, and used MatLab to investigate the needle track, velocity and acceleration when operating loop forming, tuck loop and plating. Results showed that SM8-TOP2 seamless-wear circular knitting machine can achieve diversified pattern designs by controlling the setting up of triangle, needle selection, way of threading and so on. In the knitting process, the knitting needles move smoothly, the maximum acceleration appears in the press stage and it is propitious to the forming of new loops.
