拧紧工艺的试验研究与探讨

Experimental study and discussion on tightening process

介绍了拧紧过程中转角、扭矩、轴力关系，从理论计算及实验检测两方面对扭矩法、扭矩转角法和屈服点法进行了论述。

h introduces the relationship between the angle of rotation, torque and axial force in the tightening process, discusses the torque method, the torque angle method and the yield point method from two aspects of theoretical calculation and experimental test.
