Identification of Pre-Tightening Torque Dependent Parameters for Empirical Modeling of Bolted Joints

Identification of Pre-Tightening Torque Dependent Parameters for Empirical Modeling of Bolted Joints

The vibration characteristics of bolted structures are crucially affected by the pre-tightening torque. An approach for identifying the pre-tightening torque dependent stiffness parameters of bolted joints is proposed in this paper. Firstly, the interface of the bolted joint is characterized by the...
