Analysis of Motion Response and Mechanical Characteristics of Arc-shaped Self-floating Anti-collision Device
Aiming at the problem that the guide mechanism of arc-shaped self-floating anti-collision device is prone to plastic de-formation during daily operation,the hydrodynamic analysis model of arc-shaped self-floating lifting anti-collision device based on three-dimensional potential flow theory has been established to analyze the motion response and mechanical characteristics under the combina-tion of different incident angle of wave and flow.The results show that the continuous action of water flow is beneficial to reduce the motion response of the anti-collision device.The high stiffness of the guide mechanism on the downstream side leads to a greater force while other guide mechanisms have no force or have little force.The wave incidence angle has great influence on the force of guiding mechanism.When the Angle between the wave incidence angle and the flow direction is small,the superposition effect of the wave cur-rent will increase,the guiding mechanism on the downstream side will lead to a steep increase in the axial force.
