摘要
螺纹联接副的防松在汽车结构中有着十分重要的意义。在对对顶螺母的防松效果进行力学分析的基础上，指出在实际操作中，对顶螺母不能有效地控制预紧力，也不能提高螺纹联接的强度，因此，对顶螺母不宜用于重要部位的螺纹联接。
The prevention of looseness of thread joining sets is
very vital for the structure of vehicles.In the paper,on the basis of analysizing the effects of
preventing the looseness of vertical nuts, the author points out that in reality, vertical nuts can't
control precompact forces,nor can enhance the strength of thread joining sets, and therefore can't
be suitable for thread joining of key parts.
