摘　　要：针对SR液压安全联轴器内套中间套配合应力和接触应力分析,运用弹塑性力学中的短厚壁圆筒弯曲理论和厚壁圆筒公式,分析在高压油作用下联轴器内套与中间套配合后的应力,利用理论知识计算结果与有限元处理结果进行比对,得出二者相对误差在3％～10％许用范围内,验证了所用有限元分析方法的合理与正确性,并分析出联接套配合安装的优越性.Contact stresses on the inner sleeve and the middle sleeve of SR hydraulic safety analysis are analyzed.Based on short thick-walled cylindrical bending theory and formulas in the mechanics of materials, the stress on the fit between the inner sleeve and the middle sleeve under the action of high pressure oil is analyzed, and theoretical values and measured values were compared, and their relative error is within the range of 3% to 10%. The correctness of the theoretical formula is verified. The superiority of the connecting sleeve installation is proved.
