Identification of Pre-Tightening Torque Dependent Parameters for Empirical Modeling of Bolted Joints
Publikováno v:
Applied Sciences, Vol 11, Iss 19, p 9134 (2021)
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 inte
