Analysis of the tightening process of bolted joint with a bolt heater
A bolt heater is widely used for tightening large structural members clamped by bolts with large nominal diameter, where high axial forces are required. The actual tightening operation with the bolt heater is usually done by skilled workers, since it is fairly difficult to control the axial force with high accuracy. In this study, the fundamental characteristics of the method are clarified by experiment and numerical analysis, and a numerical procedure for evaluating the tightening process is proposed using FEM as an elastic contact problem in the transient temperature field. The relationships between the heating operation and the axial force are examined for various design factors. In addition, the effects of grip length of fastened plate and nut rundown torque on axial force are also discussed. The validity of the finite element approach proposed here is ascertained by comparing numerical results to experimental ones.
