| 摘要：在引纬时，剑杆织机的碳纤剑带由传剑轮驱动，始终处于直线运动与圆弧运动的反复交替过程中。为了避免碳纤剑带开裂分层，提高使用寿命，课题组研究了碳纤剑带的刚度属性。基于梁在简单载荷作用下的力学模型，分析碳纤剑带包绕传剑轮的约束载荷特征以及影响约束载荷特征的因素。结果表明：传剑轮底径和剑带压块与传剑轮之间的间隙越小，则剑带与传剑轮之间的约束载荷越大。因此，合理设计传剑轮底径、合理设置剑带压块与传剑轮之间的间隙，对提高碳纤剑带使用寿命有较大意义。 |

| In the process of weft insertion, the carbon fiber rapier belt of the rapier loom is driven by the rapier wheel and is always in the process of repeated alternating between linear motion and circular arc motion.In order to avoid cracking and delamination of carbon fiber belt and improve its service life, the stiffness properties of carbon fiber belt were studied.Based on the beam′s deformation model under simple load, the restraint load characteristics of the carbon fiber rapier belt wrapped rapier wheel and the factors that affect the restraint load characteristics were analyzed.The results show that the smaller the bottom diameter of the rapier wheel and the gap between the rapier belt pressing block and the rapier wheel, and the greater the restraint load between the rapier belt and the rapier wheel.Therefore, a reasonable design of the bottom diameter of the rapier wheel and a reasonable setting of the gap between the rapier belt pressing block and the rapier wheel are of great significance to improve the service life of the carbon fiber rapier belt. |
