螺栓连接件中栓孔间隙分布规律的研究

The Statistical Distribution of Bolt-Hole Clearance in Bolt Joints

螺栓连接是飞机结构常用的连接方式，特别是一些重要的部件常采用这种连接方法．本文采用可靠性技术，对某种栓孔间距进行了统计分析， 从而为进一步研究栓孔间隙对连接件疲劳寿命的影响及对整机寿命的影响，提供了可靠的数据支持.

Aircraft structures, especially some important units, are commonly fabricated by the use of mechanical bolt joints. The statistic analysis of the space of bolt joints in this paper provides reliable data for the further study of the effect of the bolt-hole clearance on complete machines.
