针对L型全回转推进器在中型科考船上的结构设计问题，基于船级社关于全回转推进器支撑结构的相关规定，以中国船舶及海洋工程设计研究院（MARIC）研发的某6000吨级科考船为例，总结其船体支撑结构设计的思路和特点，并运用力法原理求解L型全回转推进器梁系简化模型，推导出船体支撑结构的承力解析解，再运用有限元方法进行验证分析，证明梁系计算结果可信、偏安全，为后续类似船型提供相对简便的载荷快速估算方法。
To hold the structure design of L-shaped azimuth thruster in the medium scientific research vessel which satisfies requirements from classification society, taking the6000tons scientific research vessel designed by MARIC as an example, summarizing the thinking and characteristic of hull support structure design and solving L-shaped azimuth thruster’s beam model through structural force method, then working out the theoretical solution of hull support structure, at last verifying the solution by means of finite element analysis, as a result, which can prove the computing result is credible and safe, and its experience can be reference for the followed vessels’ quickly load estimation.
