This paper uses the basic theoretical formulas and numerical simulation methods of filament winding process to study the influence factors between the front helical angle and the pole-diameter ratio of the large pole,the back helical angle and the pole-diameter ratio of the small pole,the stable deviation angle and the friction coefficient,analysis and dis-cussion on the winding conditions of unequal-poles pressure vessels.The friction coefficient is an important process param-eter for fiber winding,it not only affects the calculation of stable deviation angle,also affects the range of values for non-geodesic winding angles.The measurement of friction coefficient is important;it is proposed to use a comparative measure-ment method for friction coefficient in engineering applications.Finally,based on the grid strength theory,the strength cal-culation of pressure vessels is carried out,and the applicable shell thickness of pressure vessels is given using the concept of thickness-diameter ratio.Based on the full winding single angle winding process,provide a uniform strength condition for pressure vessels,and provide a theoretical basis for shoulder reinforcement in the poles winding area.
