摘要

Evaluation of the natural frequency and the natural mode of vibration of bolted joints is particularly important to avoid the failure of the structure due to resonance. In this paper, natural frequencies of the bending vibration of a bolted joint with simple configuration are measured with strain gages mounted on the surface of test specimen, and the effects of surface roughness, axial bolt force and bolt position are systematically investigated. Then, a numerical approach is proposed to analyze the free vibration problem of bolted joint, where selective reduced integration (SRI) scheme is introduced into the finite element formulation to improve the computation efficiency in solving the concerned eigen value problems. The effectiveness of the numerical procedure proposed here is validated by experimental measurements of the natural frequencies of the first mode.
