Combined Simulation Research On The Winding Device Of The Coaxial Extrusion Of A Copmpsite Wire

GF/Pb composite wire is one of the new type of composite materials and the main staples of a newly developed battery. Because of its satisfied tensile strength, good acid proof nature, fine electric conductivity and characteristics like high damp and radiation protection, GF/Pb composite wire is the key part forming the battery. So far, the manufacturing of this wire is still at the stage of continuous improvement and the techniques have not yet matured. In this thesis the forming process of GF fiber enhanced Pb base composite wire and the process of wire winding are studied to probe the interaction between the two processes and the effective law of main parameters, in order to supply theoretical instructions and fundamental data for completing the technology.In this paper, Pro/Engineer and DEFORM-3D are used to model and numerically simulate the extrusion process of this material, focusing on the relation between the extrusion force and the extrusion speed and establishing the mathematic model to be used in simulating the wire winding. Based on analyzing the mechanism of the winding device, MATLAB/Simulink is used to modeling and simulating the winding process to obtain the effective nature and the feasible region of the match weight, the resistance-frequency coefficient and extrusion force on the wire speed and the tension force.In the research, a combined simulation of plastic forming and the system dynamics of winding divice is realized based on DEFORM and MATLAB/Simulink respectively, a simulation prediction of device-technology is completed, the parameter feasible regions are determined, providing a base for industrialization of the specific equipment.
