Abstract:In order to measure the vibration range of plastic warp tube in twisting and winding process of ring spinning machine，the vibration model of the tube when it rotates at high speed is analyzed.A unidirectional vibration measurement platform is designed and a mathematical model is established to evaluate the vibration range based on the principle of the laser triangulation ranging.The best evaluation index is determined to be mean variation coefficient of the vibration range of warp tube by comparing the reflected situation on vibration range of warp tube of different indexes.The results show that the mean variation coefficient of the vibration range of warp tube varies stably，and can reflect the vibration degree more accurately.When the critical speed in the first order of the 195 mm warp tube is 6 kr/min，the mean variation coefficient of the vibration range is the largest.
Key Words:plastic；warp tube；vibration range measurement；the laser triangulation；evaluation index；sensor；calibration；mean vibration range；coefficient of variation
