摘　　要：为了提高剑杆织机引纬机构的设计灵活性和运动性能,提出了一种新型偏心圆-非圆齿轮行星轮系引纬机构。根据引纬机构的工作要求,设定了理想的剑杆运动规律,并建立了由理想引纬运动特性反求机构参数的数学模型;基于MatLab编写了该引纬机构的反求设计与仿真软件,并对该引纬机构进行参数优化和运动模拟,得到了一组较优的机构参数;最后建立了该引纬机构的三维模型,并利用机械系统动力学自动分析进行虚拟样机运动学仿真试验。实验结果显示,理论和仿真得到的剑头运动学曲线基本一致,验证了对该新型引纬机构建模和分析的正确性。To improve the design flexibility and motion performance of the weft insertion mechanism in the rapier looms,a new type of eccentric circular and non-circular planetary gear train weft insertion mechanism was presented in this paper.According to the work requirements of weft insertion mechanism,ideal rapier movement was put forward and a mathematical model for calculating the mechanism parameters from the characteristics of proposed weft insertion motion was established.The reverse design and simulation procedure of the weft insertion mechanism were compiled using MatLab,and the parameter optimization and motion simulation of the weft insertion mechanism were performed to obtain the most suitable mechanism parameters.A three-dimensional model of the weft insertion mechanism was established accordingly,and a virtual prototype kinematic simulation test was carried out using automatic dynamic analysis of mechanical systems(ADAMS).It was revealed that the kinematic curves of the rapier head based on the theoretical calculation and simulation are basically the same,which verifies the correctness of the modeling and analysis of the weft insertion mechanism.
