尾滑道式小艇收放载荷与加强结构分析

某型海警船采用的滑道式收放小艇装置,可以使工作艇快速冲上母船或脱离母船,实现小艇安全快捷地收放。文中采用动力学方法,对小艇上滑道过程的载荷进行数值模拟计算,并进行了尾滑道加强结构的强度计算分析。模型计算与实船试验表明,该船的结构加强设计满足相关要求,为相似的滑道式收放系统结构设计提供一定的参考。

Analysis of loads and strengthen structure of stern-slipway launch and recover system for jolly boat

A Patrol Ship of China Coast Guard is equipped with a stern-slipway launch and recover system which can make the working boat rush on and detach from the mother ship quickly for the secure and convenient recovery of the jolly boat. With the dynamics method, it carries out the numerical simulation of the loads during the boat rushes on the slipway and the strength analysis of the strengthened structure of the stern-slipway. The model calculation and full-scale ship trials indicate that the design adopted by strengthened structure of the ship meets the relevant requirements, which can provide references for the structure design of similar stern-slipway launch and recover systems.
