摘要: 簇绒地毯织机轴系的动不平衡是影响织机工作质量的一个因素。为了降低轴系的振动,提高织机的工作质量,本文以织机主轴模型为研究对象,采用影响系数法对簇绒地毯织机耦联主轴进行了动平衡校正。首先利用三维建模软件建立主轴模型,再经有限元软件对主轴进行柔性处理,最后结合动力学仿真软件和影响系数法对主轴的振动特性进行仿真分析。通过比较主轴校正前后的振动曲线以及轴心轨迹图,仿真结果说明了影响系数法能够明显减小主轴的振动。Abstract: The dynamic imbalance of coupling rotor in tufting carpet knitting machine is a key factor which has a negative impact on the work quality. To reduce the vibration of the shafting and improve the work quality of the loom, this paper selects loom spindle model as research object, and carries out dynamic balance correction for cou-pling spindle of the tufting carpet knitting machine with influence coefficient method. Firstly, coupling rotor model is established by three-dimensional modeling software, and then the model is dealt by finite element software, final-ly its vibration is simulated and analyzed by dynamic simulation software combining with the influence coefficient method. Comparing the spindle vibration curve and the axis orbit diagram before and after the correction, it draws the conclusion that the influence coefficient method can decrease the vibration of the spindle obviously.
