Abstract
In combining infrared (IR) thermography and the finite element method (FEM), a method is proposed for electromagnetic-thermal coupling analysis of an electromagnetic shaker armature assembly. IR thermography is used to obtain the temperature field of the armature assembly. Based on the lumped capacitance principle, this temperature field is then used to determine local convective heat transfer coefficients. FEM analysis of electromagnetic-thermal coupling is then performed using the obtained coefficients. The validity of this method is demonstrated by comparing measured and calculated transient temperature fields.
