耙吸挖泥船泥舱段结构强度的有限元分析

随着经济的发展，沿海地区的港口建设规模不断扩大，对挖泥船的需求也朝着大型化、多功能化、高自动化发展。但随着吨位的增大，大型挖泥船已超出规范尺度比的要求，因此需要对相关结构进行有限元校核。目前规范对挖泥船的有限元分析过程还没有详细的规定，因此本文结合15000m3耙吸挖泥船，对挖泥船泥舱段结构强度进行有限元分析，并提出结论。

Analysis of Trailing Suction Hopper Dredger' Cargo Structure by FEM

With the development of economic,dredgers become larger,multiple functional and automatic because of the scale of ports.However,the scale ratio of some large TSH dredger is beyond the requirement of rules,as a result,analysis of dredger’ cargo structure by FEM is necessary.But there is not any rule which apply for the FEM analysis for dredger,the calculation of TSH dredger’ cargo structure and make conclusions are supplied.
