摘要
讨论在非齐次边界条件下由端点运动激励的纱线强迫振动问题．根据生产实际中导纱器作等速横向运动的情况，应用伽辽金方法给出稳态响应的近似解，同时与运用傅立叶级数展开所得到的稳态响应的精确解通过计算与实验进行分析与比较．
This paper discusses the forced transverse vibration problem of a constant-speed travelling threadline, excited by the traverse motion of the guide- eyelet under inhomogeneous boundary conditions. First, the author uses the Galerkin's Variational method to find the approximate solution of above- mentioned equation under homogeneous boundary conditions.Secondly, numerical calculations are made by means of computer, and compared with laboratory experiments. All of them agree well.
