摘　　要：针对不控制预紧力的紧螺栓联接设计计算时需采用试算法的问题,提出一种无需试算的新方法即查表法。根据强度计算公式和插值原理编制螺栓所能承受的最大拉力表,根据拉力表便可直接查找出所需螺栓的公称直径,避免了试算法的繁琐和计算误差,简化了计算步骤,提高了计算的准确性。Simply and easy method named check table method in design of tightened bolt connection with uncontrolled tightened force is presented. According to formula of intensity and principle of insertion the maximum stretching force table which bolt can sustain is drawn up. By using the table the required bolt diameter can he determined quickly. This method can simplify the holt design procedure and give an improved calculation accuracy as compared with the trying method used now.
