影响螺旋加热弯板成形参数的研究

Investigation on Effecting Spiral Heating Plate Bending Forming Parameters

螺旋加热是船厂水火加工厚板的常用方法。本文利用ANSYS有限元分析软件对螺旋加热厚板过程进行了数值模拟,分析了螺旋加热各加工参数对厚板的温度场和变形场的影响。结果表明,加热纵向速度和板厚是螺旋加热的重要参数;与直线加热相比,螺旋加热可以在控制板表面最高温度的同时产生更深的加热深度。在船厂水火加工厚板工艺中,螺旋加热效果优于直线加热。

Spiral heating is commonly used method of line heating forming heavy hull plate in shipyard. The process of spiral heating heavy hull plate was numerically simulated by using the finite element analysis software ANSYS. Influence of the spiral heating processing parameters on temperature and deformation fields of the heavy hull plate was studied. The results indicate that, longitudinal heating velocity and plate thickness are important parameters in spiral heating;compared with the linear heating, spiral heating can control the highest temperature on plate surface and meanwhile produce deeper depth of heating. In line heating forming heavy hull plate in shipyard, the spiral heating effect is a better than the liner.
