摘　　要：通过预先计算超声滤缝合影响因子进行预测,可确定功率、压力、速度大小后再进行实际调节,简化了超声波缝纫机的调节操作过程。为此,定速拉伸超声波缝合涤纶织物缝口,比较不同因素组合下的缝口力学性能,揭示超声波花轮压力、花轮速度、功率与织物缝口力学性能的关系。结果表明:超声波花轮压力越大,花轮输送速度越低,超声波功率越大,织物缝口的力学性能越好。缝口断裂强度、断裂伸长率、断裂功与提出的超声波缝合影响因子(功率×压力/速度)呈极显著的正线性相关,该影响因子可用来表征超声波缝合织物缝口的力学性能。The adjusting procedure of ultrasonic sewing machine will be simplified accordingly by use of this ultrasonic welding factor rather than the conventional repetitive trial-error adjustments on ultrasonic power, pressure and speed of pattern roller respectively. The effects of the pressure and speed of pattern roller, and ultrasonic power on the seam mechanical properties of polyester fabric welded by ultrasonic sewing machine were studied by constant-rate stretching of the seams welded under different conditions. The results showed that better mechanical properties were achieved under higher pressure and lower speed of the pattern roller, and higher ultrasonic power. The seam strength, extension and work at break are positively correlated with the ultrasonic welding factor （ power ~ pressure/speed） , which can be used to characterize the seam mechanical properties of the welded fabric.
