The invention discloses a high-strength and high-sea-condition free falling lifeboat, and relates to the technical field of lifeboat equipment. The lifeboat comprises a lifeboat body and a lifeboat frame, the appearance design of the lifeboat body adopts a fluid-solid coupling method to control the coupling effect between a structure and a fluid, the stress distribution of the lifeboat body is simulated and analyzed, the optimal appearance is simulated and verified by combining finite element analysis and fluid mechanics results, and a plurality of safety seats, a first binding belt, a connector, a second binding belt and a third binding belt are arranged in the lifeboat body. Computational fluid mechanics, finite analysis, reliability analysis and dynamic coupling response analysis are utilized to simulate and verify the optimal lifeboat body appearance design, so it can be guaranteed that the lifeboat enters water at the optimal angle under the throwing height of 60 m, buoyancy is converted into forward impulsive force after the lifeboat leaves water at the optimal posture, the five-point type safety seat is researched and designed, members can be better fixed to a lifeboat seat,and riding safety is improved.
本发明公开了一种高强度高海况自由降落式救生艇,涉及救生艇设备技术领域,包括艇体和艇架,艇体外形设计采用流固耦合方法控制结构和流体之间的耦合作用,模拟分析救生艇体的受力分布,结合有限元分析和流体力学结果,模拟验证出最佳外形,艇体内部设有若干个安全座椅、第一绑带、连接头、第二绑带和第三绑带。本发明利用计算流体力学,有限之分析,可靠性分析,动力耦合响应分析,模拟验证最佳的艇身外形设计,使得救生艇在60米的抛落高度下,可以保证以最佳角度入水,并以最佳姿态出水后将浮力转化为向前的冲力,本发明研究设计五点式安全座椅,可以更好的将成员固定在救生艇座位上,提高乘坐的安全性。
