【摘要】 在船外板等板结构的热弯曲成型工艺中 ,用高频感应加热取代传统的火焰加热方法正得到人们的广泛重视。针对高频感应加热的特点 ,提出了感应加热热源的有限元模型。用该模型分析了高频感应加热温度场 ,并通过实验结果的比较验证了本模型的有效性。最后运用确定的热源模型对高频感应蛇形移动加热的温度场进行了有限元模拟计算 ,并对温度场进行了分析讨论更多还原

【Abstract】 High frequency induction heating has got more recognition than blaze heating in heat bend molding of shipbuilding. The article brings forward a model of the heat resource in high frequency induction heating and analyzes the temperature field. The mould’s validity was approved by experiments. A FME analysis and discussion has realized on the temperature field of snake-moving high frequency heating by using the resource model.更多还原
