关于平行运动护舷设计的思考

Study on Design of Parallel Motion Fender

平行运动护舷(PM护舷)是近年发展起来的新型护舷,在PM护舷承受偏心靠泊荷载冲击作用时基本上能保持竖直状态,从而减少桩基靠船墩等支撑结构的作用力。由于其结构比传统护舷更复杂,内部机构所承受的荷载也较难确定,在实际应用中曾发生过一些结构破坏。通过对模型试验结果的分析,水面下的锥形封闭式舷鼓可能是造成护舷结构破坏的原因之一。

The parallel motion fender （PM） is a new type of fender which is applied recently. The PM fender basically keeps vertical state when it is impacted by eccentric berthing load, which reduces the force on pile and mooring dolphin. The structure of PM fender is more complicated than that of the conventional fender, and the internal load is hard to determine. The structures of some PM fenders were damaged in service. By analyzing the modeling causes for test of underwater cone fender, it is found that the underwater enclosed rubber fender may be one of the structural damage of PM fender.
