摘要
基于纤维缠绕基础理论和数值模拟仿真方法,本文根据大封头前极孔直径比对应的螺旋缠绕角、小封头后极孔直径比对应的螺旋缠绕角、摩擦系数对应的稳定偏差角,分析讨论了不等极孔气瓶可缠绕性条件。摩擦系数是纤维缠绕的重要工艺参数,不仅影响稳定偏差角计算,也影响非测地线缠绕角的取值范围;摩擦系数测量至关重要,本文提出采用摩擦系数对比测量方法进行工程应用摩擦系数的测量。基于网格强度理论压力容器强度计算,采用厚径比概念给出薄壳压力容器壳体设计厚度的适用范围;最后,结合全缠单角缠绕工艺,给出压力容器不同截面处的匀衡强度条件,为封头缠绕区的肩部补强提供理论基础和工艺路线。
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.
