针对电磁感应加热瓦楞辊的结构尺寸与加热功率关系不明，结构设计和电磁热耦合仿真时，其材料、结构尺寸的 选取缺乏直观依据的问题，提出了基于磁路原理的瓦楞辊结构的磁路模型，在忽略漏磁和磁饱和前提下，导出了感应加 热的理论功率与瓦楞辊的结构尺寸、材料性质和所通感应电流的关系，给出了具体的解析表达式，并且仿真分析了磁导 率对加热功率的影响，为瓦楞辊的设计提供了一种思路，减少了有限元结构仿真时材质和结构尺寸选取的盲目性。

Magnetic Circuit Model of Induction Heating Corrugated Roller

lt is lack of intuitive basis how to select materials and sizes when design the structure or do electromagnetic thermal coupling simulation of corrugating roller. because the relationships are unknown between the structure size and the heating power of electromagnetic induction heating corrugating roller. To solve the problem, this paper put forward the magnetic circuit model of corrugated roller based on the principle of magnetic circuit. Then under the premise that ignored magnetic flux leakage and magnetic saturation. the relationship was induced between the theory power and the size of structure. material properties and conduction currents in induction rollers. And more. the analytical expression was given, the simulating results show how the permeability of material affects the heating power, which provides a new way for the design of corrugated roller. and reduces the blindness in selecting material and structure size with the finite element software.
