2000t级内河石油沥青船温度场及热应力分析

Analysis on temperature field and thermal stress of a 2 000 t inland river petroleum asphalt ship

以2 000 t级石油沥青船为研究对象,采用MSC/PATRAN和MSC/NASTRAN有限元软件,建立有限元模型,考虑温度应力场影响,对石油沥青船的2种工况进行了分析。研究结果对同类船舶的温度场计算和热应力分析具有一定的借鉴意义。

Using 2 000 t petroleum asphalt ship as a research object,the paper adopts MSC / PATRAN and MSC / NASTRAN finite element software,establishing finite element model,considering influence of temperature stress field,it analyzes two kinds of condition of the petroleum asphalt ship. The results of the research has a definite reference significance for temperature field and thermal stress analysis of similar ship.
