摘　　要：为进一步提高纺纱锭子的转速及纺纱效率,通过仿真分析和实验的方法,研究了锭子的上轴承挡直径、下轴承挡直径、支撑距和锭带挡直径等结构参数对锭子临界转速和锭端振幅的影响。结果表明:上轴承挡直径减小,锭子的临界转速先减小后增大;锭端振幅随着上轴承挡直径减小而振荡增加,随下轴承挡直径减小而直接减小,随锭带挡直径减小在一定范围内波动,随支撑距减小呈现先减小后增加的变化趋势;减小上、下轴承挡直径、支撑距和锭带挡直径后,锭子转速提高约5.5%,且锭端振幅略有减小;临界转速和锭端振幅的仿真结果与实验结果基本一致,验证了仿真模型及参数设置的正确性。结果可为锭子的优化设计提供理论参考。In order to increase spindle rotation speed and spinning efficiency,by combining simulation analysis and experiment verification,this paper studies the effects of the structural parameters of a spindle on its critical rotation speed and spindle end amplitude,such as the spindle’s upper bearing diameter,lower bearing diameter,support distance and spindle belt diameter.Results show that the diameter of the upper bearing decreases,and the critical rotation speed of the spindle decreases first and then increases.The amplitude of spindle end vibrates increasingly with the decrease of the diameter of the upper bearing,but decreases directly with the decrease of the diameter of the lower bearing.As the spindle belt diameter decreases,the amplitude remains with in a certain range.With a decrease in support distance,the amplitude decreases first and then increases.When the diameters of upper and lower bearings,support distance and the spindle belt diameter reduce,the spindle rotation speed increases by about 5.5%,and the spindle end amplitude reduces slightly.The simulation and experimental results of the critical rotation speed and spindle end amplitude are basically consistent,which verifies the correctness of the simulation model and parameter setting.The results provide theoretical reference for spindle design and optimization.
