基于仿真分析的工作艇吊艇架选型设计

Type Selection and Design of Workboat Davit Based on Dynamic Simulation

根据用户在给定海况条件下安全收放工作艇的需求,对某船所配设的工作艇吊艇架进行选型,并参照规范要求进行设计布置;采用ANSYS AQWA软件,考虑船与工作艇的耦合作用对其在给定海况条件下的运动幅值等进行动态仿真分析,得出吊艇架具备安全作业的条件、作业时间窗口等;经实船试验验证,满足用户及规范、法规的要求。

Based on the requirement of the users of safely stowing&releasing of workboat under the given sea condition,the type selection of boat davits for a ship and layout design according to the rules are carried out,considering the coupling effect between the ship and workboat,the dynamic simulation analysis of the motion amplitude under the given sea condition in a certain time domain is conducted by using the ANSYS AQWA software,and finally the working conditions&job time window for the operation security of safely stowing and releasing of workboat by boat davit are obtained.Verified by the test of stowing and releasing workboat of the actual ship,the selected workboat davit meets the requirements of the users,rules and regulations.
