摘　　要：为给高质量簇绒地毯的开发提供设备保障,针对运动副铰链中存在间隙的问题,以DHGN801D-400型簇绒地毯织机耦联轴系的主轴系统为研究对象,介绍了簇绒地毯织机耦联轴系的组成部分,分析了针机构的运动特性。考虑到簇绒针机构中3处易磨损的铰链间隙,基于虚拟样机ADAMS软件得到不同间隙下簇绒针的位移、速度、加速度及铰链支反力,从而根据针位移分析铰链间隙对毯面绒高的影响。再以铰链点坐标及杆长为设计变量,以铰链副间的冲击力和针行程最小为优化目标,对该簇绒针机构进行多目标优化,得到最优的铰链坐标及杆长,将铰链间隙对绒高的影响降到最低。Focusing on tufting machine type of DHUN801D-400 and based on the problem of joint clearances in kinematic pairs,the joint clearances of coupling shafts system in needle mechanism are studied.Firstly,the structure of coupling shaft system in tufting machine is introduced and kinematic analysis is studied.Secondly,the three joints with clearance are considered in needle mechanism.And the displacement,velocity,acceleration and reaction force between kinematic pairs in needle mechanism under different clearances are obtained using the ADMAS software,then the impact on pile height is obtained according to the displacement of needles.Thirdly,regarding the coordinates of hinged points and length of bars as design variables,the reaction force and stroke of needles as objective function,the multi-objective optimization is carried out.Finally,the optimal hinge coordinates and the length of bars are obtained,and the influence of joints clearance on pile height is decreased to lowest.
