Hydraulic expansion bolt is being widely used in modem naval shafting system due to its convenience in assembly/disassembly and good performance in large torque transmission. Based on nonlinear contact theory, a finite element model of a hydraulic expansion bolt was built. The distribution of the contact stress was obtained in the working condition of the maximum torque transmission. Furthermore, based on modern impact theory, an anti-shock model of the hydraulic expansion bolt was built to simulate its anti-shock performance in frequency domain and time domain with the consideration of the contact stress. The stress obtained from the anti-shock simulation can be used for anti-shock design and evaluation. The results indicate that the design of hydraulic expansion bolt can meet the anti-shock requirement.
