The study of vortex induced vibration under high Reynolds number is of great importance. While flow sensors are generally fixed to structures, it is of great practical importance to analyze and simulate the measurement information under vibration conditions. In this study, the subcritical Reynolds number three-dimensional flow and vortex-induced vibration of a cylinder are simulated and analyzed using the translational moving reference coordinate method together with a self-developed fluid computation program. The results show that the method accurately simulates the vortex-induced vibration phenomenon.It is found that the phase difference between the lift and the displacement produced a jump within the VIV lock-in region, and the vortex broke up during the vibration, showing strong three-dimensional characteristics. Time-averaged physical quantities near the wall and the wake region were obtained by statistical calculation of the grid in the translational reference frame. The simulation method based on the translational reference system is similar to the observation method of sensors attached to the structure in experiment and on-site testing, which can provide references to model tests and field measurements.
