摘要以共轭凸轮引纬机构的连杆材料45钢、铝合金、铜合金和铸铁为研究对象，以带间隙共轭凸轮引纬机构为研究平台，进行了机构运动仿真，得到了剑带的运动特性曲线。通过比较机构刚性时的特性曲线，得出了机构刚性时的差异曲线。考虑到材料本身的特性，利用ADMAS软件对不同材料的连杆进行了极限载荷分析。在ANSYS中对柔性构件施加极限载荷时，通过对应变云图的分析，给出了材料特性对连杆运动特性和变形的影响。当选用铝合金时，运动特性最好，连杆机构变形不明显。
Abstract 45 steel, aluminium alloy, copper alloy and cast iron were selected as the materials of the connecting rods of the conjugate cam weft insertion mechanism as the research object and the conjugate cam weft insertion mechanism with clearance as the research platform, the simulation of mechanical movement was conducted and the kinetic characteristic curves of the sword belt were obtained. The difference curves were drawn by comparing the characteristic curves when the mechanism was rigid. Considering the properties of the material itself, the ultimate load of the connecting rods in different materials was analysed with ADMAS. Under the ultimate load on the flexible component in ANSYS, the influence of the material properties on kinetic characteristics and the deformation of the connecting rods were provided based on the analysis of the strain nephograms. The characteristics of the movement were the best and the deformation of connecting rod mechanism was not much obvious when aluminium alloy was selected.
