波浪自适应救助艇收放连接装置设计

Design of Retracting and Releasing Connecting Device for Wave Adaptive Rescue Boat

为有效缓解风浪对高海况下波浪自适应救助艇收放作业的影响,提升其安全性和稳定性,针对双体船波浪自适应救助艇特殊的船体结构,设计与其适配的连接装置,根据五级海况下的工作条件和收放要求对连接装置自身结构及与船体装配之后的整体结构进行强度校核,验证连接装置的强度满足设计要求和安装位置的合理性。通过搭建收放系统整体的动力学模型得到连接装置在收放过程中的动态强度,保证其能在五级海况下实现对波浪自适应救助艇的收放。

In order to effectively decrease the impact of wind and waves on the deployment of wave adaptive rescue boat under high sea conditions,and to improve the safety and stability of the boat,a connection device for the special hull structure of catamaran wave adaptive rescue boats is designed.The strength of the device itself and the overall structure after assembly with the hull are checked to verify that the strength of the device meets the requirements and the rationality of the installation position according to the working conditions and deployment requirements under Level 5 sea states,and the dynamic strength of the device during the retract and release process is obtained with the overall dynamic model of the retract and release system,which ensures the connecting device to achieve wave adaptive retract and release of the rescue boat under Level 5 sea states.
