摘　　要：文中针对小尺寸闭式过盈联接型膜盘联轴器联接单元配合压力设计应用不便、数值计算繁复这一问题,通过研究已有文献关于闭式过盈联接装配压力数学模型通解的特点,构建了薄壁闭式过盈配合压力分布的解析计算公式,求解了各待定系数,给出了联接单元和膜盘结合处弯矩和剪力的求解方法,实现了大非线性过盈配合压力的解析表达。最后,通过算例分析验证了解析式的正确性,极大地方便了该过盈连接的设计与应用。Since such problems as inconvenient application and complicated numerical calculation are found in the design of fit pressure of diaphragm coupling with small-size closed interference structures,this article focuses on the characteristics of the general solution of the assembly-pressure mathematical model of the closed interference joint,which are discussed in the current literature;the analytical formula for pressure distribution of the thin-walled closed interference joint is worked out,the undetermined coefficients are solved,and the method of how to solve the bending moment and the shear force at the interference structure and the diaphragm joint is given,and thus the analytical expression of large non-linear interference fit pressure is realized. Finally,an example is given to verify that the analytical formula is correct,which greatly facilitates the design and application of interference joint.
