中文摘要:
      针对不同波源下微波加热多层橡胶复合材料，建立基于Maxwell方程的一维非稳态有源加热偏微分方程（PDE）模型，以丁苯橡胶材料和丁腈橡胶材料复合为例，采用时域有限差分法进行模拟仿真，研究多层（两层）橡胶复合材料在单/双波源下材料厚度和微波功率对加热温度场和界面特性的影响。结果表明：微波功率变化会影响多层橡胶复合材料加热温度分布；在叠加橡胶材料的交界面处，微波振幅会有微小变化；将介电损耗小的橡胶材料直接暴露于微波源，有利于微波穿过介电损耗小的橡胶材料向深处传播，且各层橡胶材料厚度宜控制在临界穿透深度以下；相对于单波源加热，多波源加热能改善多层橡胶复合材料加热的均匀性。与传统有限元模型的分析结果进行比较，验证了本研究模型的有效性。
英文摘要:
      One-dimensional unsteady finite element heating PDE model based on Maxwell equation was established for microwave heating of multilayer rubber composites under different wave sources. Taking SBR material and NBR material complexing as examples，the effects of material thickness and microwave power on the temperature field and interface characteristics of multilayer（two-layer）rubber under single/double wave sources were simulated by the finite-difference time-domain method. The results showed that the change of microwave power would affect the temperature distribution of multilayer rubber composite. The microwave amplitude would change slightly at the interface of multilayered rubber materials. The rubber materials with small dielectric loss should be directly exposed to the microwave source，which was conducive to the penetration of microwave. The thickness of each rubber layer should be controlled below the critical penetration depth. Compared with single source microwave heating，use of multi-source microwave heating could improve the heating uniformity. The model validity of this study was verified by comparison with the results of the traditional finite element model.
