力矩控制在雷达装配中的应用

通过适当的拧紧力矩来控制螺纹装配预紧力是一项重要的装配技术,也是机械装配中的难点.我国在力矩控制方面虽然开展了一些研究,但现有的大部分拧紧力矩标准主要从螺栓强度等级角度列出了力矩数值表,并没有从应用对象、被连接件角度考虑力矩的控制量.文中梳理了雷达装配过程中力矩控制应用的需求对象,讨论了力矩控制工程应用理论基础和力矩确定原则.

Application of Torque Control in Radar Assembly

Using appropriate tightening torque to control screw assembly pre-tightening force is an important assembly technology, it is also a difficult point in mechanical assembly. Some researches on torque control have been carried out in our nation, but most of tightening torque standards just list the numerical torque values according to screw strength levels, the degree of torque control is not considered from the perspectives of application objects and connected parts. In this paper, the objects needing torque control in radar assembly procedure are listed, the basic theory of torque control engineering application and the determination principle of torque value are discussed.
