橡胶微波加热硫化的有限元分析

运用有限单元法求解Maxwell方程和传热方程，并采用ANSYS有限元软件计算和分析橡胶传统的热量由外向内传递的加热过程和微波加热过程。结果表明：微波加热硫化橡胶加热时间短，效率高·橡胶内的电场强度分布、焦耳热密度分布和温度分布都不均匀；随着微波加热时间的延长，胶料内的温度提高，但处于较高硫化温度的胶料范围几乎无变化。;Finite element method was used to solve Maxwell equations and heat transfer equation，and ANSYS finite element software was used to calculate and analyze the process of conventional heating in which heat transferred from outside to inside，and microwave heating process of rubber.The results showed that the time of microwave heating was shorter and the efficiency was higher.By using microwave heating，the distributions of electric field strength，Joule heat density and temperature were uneven.With heating time extending，the temperature of rubber increased，while the range of rubber which was at high curing temperature was almost unchanged
