Study on the Dynamic Characteristics of Warp in the Process of Weaving

The fluctuation process of warp movement is analysed by the nonlinear vibration method. Based on Newton’s Law, a differential equation of warp axial/cross direction movement is established. This paper separates the time variable from the space variable by the variable-separating method, then it gives a numerical solution of the motion equation by the fourth-order Runge-Kutta method. Also this paper discusses influencing factors and vari able trends for warp vibration. Finally a method for the control of vibration is introduced.
