The aim of this study is to parametrically analyze the vibration characteristics of weaving needles during the feeding motion, providing effective references for the selection of parameters in the three-dimensional weaving process. To control the degree of carbon fiber wear during the manufacturing process and maximize its maximum forming height, we have established a systematic dynamic model based on Hamilton's principle. The state equation was solved using the Runge-Kutta method. The influence of different weaving parameters on the weaving needle‘s free-end vibration response and equilibrium position of was studied. The results indicate that the weaving velocity and height of the cross-section have a significant impact on the vibration amplitude of the free end of the weaving needle and the deflection of the equilibrium position. Moreover, the increase in deflection exhibits a certain inhibitory effect on the amplitude.
