摘　　要：由于剑杆织机在高速运转时不可避免的产生柔性,只考虑曲柄的柔性,通过改变曲柄的材料,在ANSYS中生成相应曲柄的中性文件,采用ANSYS-ADAMS联合仿真的方法,把中性文件导入ADAMS中分别进行仿真。在仿真得到不同曲柄材料下剑带的运动特性曲线后,通过分析比较,发现改变曲柄材料对剑带运动特性曲线的影响。仿真结果表明:在考虑构件柔性的情况下,合理选择曲柄的材料,可以大大的减少柔性件对空间四杆引纬机构的影响,从而提高织物的质量。Because of the flexible question of rapier loom at high speed, this paper was considered only the flexibil- ity of the crank by changing the crank material. With the method of ANSYS-ADAMS co-simulation, corresponding neutral documents generated in ANSYS were imported into ADAMS for simulation to receive the motion curves of sword belt. Through the analysis and comparison, the relationship of changing the crank material and the motion curves of sword belt were found. The simulation results show that, in consideration of the flexible components, ra- tional selection of crank material can greatly reduce the impact on spatial four bar linkage weft insertion mechanism, thereby enhance the quality of the fabric.
