文摘

Bolt pre-tightening force and the characteristics of contact surfaces have great influence on structural modes and transfer functions, which are usually ignored due to the difficulty in treatment. Using the ANSYS Workbench software, the finite element model of the whole structure and the bolt connection structure are established, and the vibration modes and harmonic responses in different structures are investigated. By comparing the finite element calculation data and test data, the influence of bolt connection structure is analyzed. Comparing the results when the bolt pre-tightening force is varied, the results show that the natural frequencies of bolt connection structure decrease compared with the whole structure. The transfer characteristics of the system are influenced by the pre-tightening force, and the natural frequencies increase with the increase in pre-tightening force.
