摘要

Bolted joints are widely used in industry. One of the common applications is to connect the rotor disks and drums in aero-engines. Finite Element (FE) method is one of the most effective tools for predicting nonlinear behaviours of bolted joints. However, FE models for bolted disk-drum joints usually require large memory and computational time. In this paper, a non-contact model of much higher efficiency is developed. Firstly, the formula for nonlinear axial stiffness of the bolted disk-drum joints is derived. Then, the nonlinear stiffness is represented by spring elements at the joint interface to construct the non-contact model. Finally, the accuracy and efficiency of the non-contact model are evaluated by comparing the simulation results from the 3D contact model and the non-contact model. It is revealed that the non-contact model improves the computational efficiency significantly, and the simulation results of the non-contact model show sound agreement with those calculated from the contact model.
