为改善钢板感应加热成形，建立了钢板感应加热成形的数学模拟模型，验证了感应加热用于钢板热应力成形的可行性，并针对加热过程中影响成形效果的重要因素，研究了其变形影响规律。基于电磁场理论，利用有限元软件ansys建立了钢板感应加热的有限元模型。利用Rogowski线圈测量了感应加热过程中感应器内的电流强度和频率，从而确定了感应加热过程中的电流强度和频率。结果表明：延长感应加热时间或增加感应加热电流强度均可增大横向收缩变形，通过调整感应加热过程中的电气参数和加热时间可获得合理的变形。
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 measured with the use of a Rogowski coil,thus,electrical parameters useful in numerical calculation were obtained.The calculation results were consistent with experimental values.The following conclusions were made: the transverse shrinkage deformation can be increased by either prolonging the induction heating time or increasing the current intensity in the inductor.Reasonable deformation can be achieved through the adjustment of electrical parameters and heating time in the induction heating process.
