摘要
基于固有变形理论和弹性有限元分析,以氧-乙炔火焰加热的固有变形为输入参数,应用弹性有限元分析预测船体板材的面外变形;对比两种不同加热模式下板材受热弯曲成形的效率。研究分析表明,弹性有限元分析可高效地预测板材成形的效果,且从边缘到边缘的平行线加热模式,更有利于板材的弯曲成形。
The intrinsic deformation of oxygen acetylene flame heating is taken as input parameter based on the theory of internal deformation and elastic finite element analysis. The efficiency of ship plate bending under two different heating models is compared, it can be drawn that elastic finite element analysis can be used to predict ship plate bending effectively and it is better for plate bending with parallel heating pattern.
