摘要
本文认为螺栓相对刚度对螺栓强度的影响需具体分析。对螺栓拉伸强度计算的载荷系数法作了进一步探讨。对螺栓强度计算、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计算给出了计算公式，同时给出了各种情况下三角螺纹的最大螺牙载荷及其回归公式。
This paper thinks that the influence on bolting fatigue strength by bolt relative rigidity must be analyed specificly, and gives the additional remarks to load coefficient method of calculating bolt tensile strength. It is very necessary that leading calculation of the maximum tensile stress of screw-tooth roots onto the bolt strength calculation. This paper also gives the calculation formulae that based on similar theory and boundary unit calculation, and the maximum tooth load and its regressive formulae under various situations of triangle screwthread.
