摘　　要：对螺栓拉伸强度计算的载荷系数法作了进一步改进。对螺栓强度计算提出：应再引入牙根最大拉应力计算内容，并根据相似理论和边界元法给出了计算公式。同时给出了各种情况下普通螺纹的最大螺牙载荷百分率及其回归公式。The load coefficient method of bolt on tensile strength calculation was improved. For bolt tensile strength calculation must consider of the maximum tensile stress of screw tooth roots in addition. This paper also gives the calculating formulae that based on theory of similarity and boundary unit calculation, and the maximum tooth load percentage and its regressive formulae under various situations of triangle screwthread.
