Prediction model for nonlinear variation of bolt preload with tightening torque based on mechanism and data fusion

Prediction model for nonlinear variation of bolt preload with tightening torque based on mechanism and data fusion

Abstract In response to the difficulty in predicting the change of bolt preload when using torque method to load bolt, this paper proposes a bolt preload prediction method based on mechanism and data fusion calculation for hexagonal end face bolt, and establishes a tightening prediction model based...
