Analysis of the Tightening Process of an Asymmetrical Multi-Bolted Connection

The paper deals with modelling and calculations of a multi-bolted connection characterized by an asymmetric arrangement of bolts. Equations of system equilibrium on the preloading stage of the connection are described. The iterative algorithm of the computational process is presented, which is related to both nonlinearity of spring elements used for modelling of the contact layer between joined elements and one-sidedness of constraints imposed on the connection. Results of calculations of the selected multi-bolted connection are presented.
