摘　　要：为了提高簇绒地毯品质,正确了解不同区域内纱线振动特性显得尤为重要。针对不同路径上的纱线束,采用牛顿第二定律建立了纱线横向振动方程,得到不同区域的纱线振动特性曲线及振动频率。介绍了簇绒地毯装备系统的组成,并对纱线路径进行了划分;对纱线微元段进行受力分析,建立纱线横向振动方程,并采用Galerkin截断法将振动偏微分方程变为常微分方程,利用Runge-Kutta方法对方程进行数值求解,得到不同区域内的纱线振动振动频率,并着重分析了经过提花部件后的纱线特性。结果表明,纱线经过提花部件后,纱线的最大振幅为3.75 mm,对提花地毯品质的影响较大。To improve the quality of tufting carpet, it is important to understand the vibration characteristics of yarn in different positions. The transverse vibration equation of yarn is established with the Newton＇s second law, thus the curves of vibration characteristics and natural frequencies are obtained. The composition of tufting machine is introduced and the yarn path is divided into different regions. The force of yarn element is analyzed and the transverse vibration equation of yarn is built. The partial equation is transferred into the differential equation by Galerkin truncation method and the equation is solved by the Runge-Kutta. Therefore, vibration frequencies in different regions are obtained, and the vibration characteristics of yarn after jacquard parts are analyzed emphatically. The results show that the maximum amplitude of yarn is 3.75 mm, having great influence on the quality of tufted carpet.
