| 摘 要： | 针对船体曲面板的感应加热成形方法,研究钢板感应加热的数值模拟模型,确定感应热源应用于钢板热应力成形技术的可行性,以及加热过程中的主要影响因素对于变形的影响规律.依据电磁场理论,基于ANSYS软件建立了钢板感应加热有限元模型,利用罗氏线圈测量加热过程中感应器的电流强度和频率,从而得到了数值计算时的电学参数,实验结果和数值模拟结果相吻合.结果表明:随着感应加热时间的延长,横向收缩变形增大,当感应器中的电流强度增大时横向收缩变形也增大,通过控制加热过程的电学参数和加热时间可以得到合理的变形要求.

| Abstract: | To improve induction heat forming of steel plate,a mathematical simulation model was investigated.This confirmed the feasibility of using induction heating for steel plate heat stress shaping,and the deformation effect rule was studied for significant factors influencing results during the heating process.Based on electromagnetic field theory,a finite element model for steel plate induction heating was built up by means of ANSYS software.Current intensity and frequency in the inductor during induction were ... |
