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.
