摘　　要：利用有限元分析方法,结合低松弛预应力钢绞线生产工艺,对其感应加热系统进行建模并分析钢绞线内部温度场的分布;分析了在改变加热电源的频率情况下钢绞线的温度分布及其大小的变化。结果表明:电源频率是感应加热中极其重要的影响参数。A model of induction heating system was established and the temperature field of the strand steel wire was calculated by using finite element analysis,along with low-relaxation prestressed strands process.By changing the frequency of heating supply,temperature field was changed significantly in the strand steel wire.The results show that the frequency is an important influential parameter in induction heating system.
