基于HCSR与CSR的船底砰击结构评估方法研究

Bottom slamming structure evaluation method research based on HCSR and CSR

根据协调共同规范(HCSR)与共同规范(CSR),对30万吨级原油船底部砰击结构进行评估研究;通过规范计算、有限元建模、边界条件选取,载荷确定与施加、结果评估等方面的对比分析,优化由于底部砰击所造成板厚激增的船首结构,减轻空船重量,减低建筑成本。

Based on coordinate joint specification（HCSR） and common specification（CSR）,bottom slamming structure evaluation research of 30 ton crude oil tanker is carried out. With standard calculation,finite element modeling,boundary conditions,the applied load, the results of evaluation of determination and comparison analysis, optimize the thickness surge of bow structures caused by bottom slamming, reduce light weight and construction cost.
