[Abstract]:Winding tension as a key factor in winding process, its reasonable design directly affects the performance of products.According to the design of winding tension, a winding tension algorithm is proposed.Based on the theory of elastic deformation of anisotropic winding layer and isotropic thick-walled cylinder, the radial and circumferential stresses of the winding layer under external pressure are given.In the elastic range, the stress superposition principle is used to establish the analytical algorithm between the residual tension and the winding tension.Combined with three typical tension winding models, the concrete relation formula of residual tension is given, and the analytical formula of residual tension under different special cases is obtained by analyzing the same residual tension.According to the analytical algorithm, the influence of the outer diameter ratio and the tension taper coefficient on the distribution of residual tension in the winding layer of isotropic material is studied. It is shown that the variation of the outer diameter ratio and the taper coefficient in the core mold has a significant effect on the residual tension distribution of the winding layer.The algorithm is simple, reasonable and reliable, and the results of the analysis of the residual tension of the anisotropic composite winding layer are consistent with the existing mesh theory, and the change of the upper and lower layers of the winding tension is gentle, which is easy to control the tension.
