Abstract

Abstract: In this paper, the design and process research of uniform filling linear trajectory for filament wound vessel with unequal polar holes are carried out. Firstly, the winding angle of left and right heads is smoothly and continuously transited in the cylinder by optimizing the slip coefficient. The necessary conditions for realizing the central angle of uniform filling are studied, and the tangent points of the line are calculated by using the continuous fraction principle. At the same time, the slip coefficient of the left and right ends of the stable winding and uniform covering is satisfied. Based on the equal contour constraint conditions, the motion trajectory equation of the four axis winding machine is analyzed and converted into the corresponding machine code for actual winding. The experimental results show that the stable winding of the fiber on the surface of the unequal polar hole mandrel is realized, and the uniform filling and winding effect are achieved after winding a certain number of cycles. The simulation results show that the design parameters and optimization algorithm are feasible.
