| 摘要: |
| 干涉配合可大幅度提高接头疲劳寿命。对基于应力波加载的钛合金干涉螺栓的高速安装过程进行了理论分析，对其安装工艺参数进行研究。研究表明：基于应力波加载的高速安装方法的安装阻力明显小于同等条件下准静态安装方法的安装阻力，干涉量1%、1.5%和2%下最大安装阻力分别为3.92 kN、5.64 kN和6.11 kN；安装阻力随干涉量和安装次数增加而升高，随加载速度增加而降低；多次安装容易造成孔壁划伤，同时发现加载速度过大容易引起螺栓头损伤；干涉配合紧固件安装时孔边最大凸瘤高度与干涉量、安装速度和安装次数、摩擦因数正相关。 |

| Abstract: |
| Interference-fit technology can significantly improve the fatigue life of bolted joints. In this study, based on the stress-wave driving technology, the high-speed driving process of titanium hi-lock bolts was analyzed theoretically, and the process parameters of driving were studied. The results show that the driving resistance of M8 titanium hi-lock bolts for the stress-wave driving is significantly lower than that of static driving under the same condition. The maximum values of the driving resistance under the interference sizes of 1%, 1.5% and 2% are respectively 3.92KN, 5.64KN, and 6.11KN. The installation resistance increases with interference sizes and driving times, while increases against with driving speeds. However, hole crash can be found under several times installation and the damage of bolt head can occur under the higher installation speeds. The maximum height of protuberance increases with interference sizes, driving speeds, driving times and friction coefficients. |
