船体温度分布及温度应力计算

The Temperature Distribution and Thermal Stress Analysis of Ship Structures

本文提出一种适于在船舶设计中使用的船体温度分布和温度应力的计算方法．本法采用变剖面薄壁梁船体模型，船体的温度分布根据热传导理论计算，船体的温度应力根据弹性理论处理平板温度应力问题的思想，并结合梁弯曲的有限元法计算．

Based on the theory of heat conduction, theory of elasticity on thermal stress analysis for plate and FEM for beam bending, a calculation approach for temperature distribution and thermal stress evaluation of ship structrues is presented in this paper, where the ship hull girder is treated as thin-walled beam with variable cross sections.
