It is found that the temperature of bolt increases sharply to the melting point under the adiabatic condition.
结果表明：在绝热条件下，螺栓结构温度持续升高，直至接近熔点；
Then the paper presented where the first danger point of joint bolt taken place under working stage, and checked fatigue stress life of the bolt.
得出了螺栓工作状态下最危险点发生的位置，考核了螺栓的疲劳强度安全系数，分析结果表明，螺纹连接是一种弹塑性模型。
