齿轮槽头型新型标准件安装工艺与试验研究

Study on Process and Experiments of Installation for Gear–Recessed-Head Bolt

航空制造领域大量采用了如螺栓连接的标准件连接,随着新型飞机性能的提高,长寿命、高疲劳强度和高振动环境等指标对标准件的使用提出了更高的要求。本文通过开展齿轮槽头型新型标准件安装工艺与试验研究,一方面确定了该型标准件安装力矩等关键工艺参数及对复合材料的适用性,为其装机和使用提供理论依据及数据支持;另一方面,也对开展新型标准件安装工艺与试验的研究方法进行了有益的探索,对逐步形成一套完善的试验方法规范具有很好的指导作用。

Based on studying the process and experiments of installation for gear–recessed-head bolts, a series of key technological parameters like installation moment, etc are proposed.are proposed, which provides theoretical and data supports. On the other hand, a feasible way to study the technological parameters of the new type standard fasteners is explored through experiments, which helps to form a study and experiment specifi cation in the future.
