摘要:This paper simulates the conical oscillating float by hydrodynamic calculation software. It mainly focuses on the modelling and simulation of the float cone angle, and analyses the frequency domain of the respective radiation damping, added mass, exciting force and Response Amplitude Operators (RAOs). The results show that when the frequency is greater than 0.9Hz, the exciting force and the added mass of the float are smaller. When the frequency is less than 0.6 Hz, the radiation damping increases as the wave frequency increases, RAOs will change slightly. When the frequency is greater than 0.6 Hz, the radiation damping and RAOs decrease as the frequency increases. For an oscillating float of the same mass and different cone angles, the added mass reaches a maximum value when the wave frequency is about 0.2 Hz, and the added mass change is small when the frequency is greater than 0.9 Hz.
