编带机锭子运动轨道曲线分析

锭子运动的轨道由直线和曲线两部分交替组成。锭子沿轨道运动时 ,由于速度、加速度的变化 ,使锭子与轨道间产生冲击和噪声 ,降低它们的使用寿命。加速度变化愈大 ,冲击力及噪声愈大。引起加速度变化的原因主要是轨道曲线形状。不同的曲线形状 ,加速度变化量不同。本文分析锭子运动轨道曲线的目的就是选用最佳曲线。通过分析 ,得到不同曲线的加速度变化量。比较确定 ,轨道曲线做成抛物线优于其它形状的曲线。抛物线形状简单、加工方便 ,锭子加速变化小。该结论可供生产、科研单位参考、借鉴

Analysis of Motion Trajectory of Weaving Machine Spindle

Track of spindle consists of straight line and curve line in turn.When spindle moves along the track,with the change of velocity and acceleration,chang lash and noise produced between spindle and track would reduce their service life.The greater the acceleration changes,the greater the lash and noise will.The be reason for acceleration change is curve of the track.When curve line is different,the change of acceleration is different.The purpose of analysing spindle motion curve line is to select the best curve line.By analysis,we have got acceleration changes of different curve lines.Parabola is the best curve line because it is simple,easy to make and the Changes making of spindle's acceleration is smaller.The conclusoin can be used for reference by and scientific reseach institudes.
