摘要
应用感应加热理论,建立了电磁场与温度场耦合的有限元数学模型,利用通用有限元软件ANSYS对大型半组合式船用曲轴曲拐感应加热过程进行了模拟分析,得到了随时间变化的工件温度与变形分布图,并分析了感应加热整个温升过程的特点与影响因素,结果表明,通过调整加热装置的频率、电流强度、加热位置等工艺参数,可以建立优化的曲轴红套加热工艺。
Based on the induction heating theory,a finite elementmodel for electromagnetic-temperature field has been developed.The simulation of induction hardening process in Large Size Crankshaft shrink fitting is carried out by using FEA software ANSYS with temperature and deformation distribution calculated,the characteristics and effect factors in the induction heating process also are analyzed.In conclusion,the optimized crankshaft heating techonology could be estabished by adjusting technological parameters of the heating device.Specifically,frequency,current,heating position and so on.
