摘 要:In this paper,a method about the water-entry slamming of a two-dimensional(2D)bow structure has been proposed based on the experimental and simulation *** to this method,the sensitivity analysis has been carried out about the effect of speed and inclination angle on the slamming pressure of the ***,a 2D ship bow experimental model was performed to obtain the slamming pressure distribution at different measuring points under different ***,numerical simulation for the water-entry slamming of this experimental model was conducted to obtain the pressure distribution on the experimental model under different working ***,the experimental results were compared with the numerical simulation results to evaluate the effect of speed and inclination angle on the slamming pressure of the *** results show that the slamming pressure is more sensitive to speed variation within the low-speed *** effect of inclination angle on the slamming pressure is more obvious in the small angle *** the inclination angle is larger than 45°,the effect is limited.
