在对管模生产条件下的热态工况进行分析的基础上 ,利用有限元数值模拟方法首次建立了管模传热分析轴对称模型。在模型中对管模传热系统中的对流、辐射、接触边界条件和凝固潜热进行了处理 ,利用有限元分析软件ANSYS ,分析了2 1CrMo10 (德国牌号 )材料管模的温度场、热应力场的变化。数值模拟结果与试验测量结果以及实际生产中管模的破坏状况相符合。
Based on the analysis of the hot working conditions under the condition of tube mold production, the axial symmetry model of tube mold heat transfer analysis was established for the first time by using the method of finite element numerical simulation. In the model, the convection, radiation, contact boundary conditions and latent heat of solidification in the heat transfer system were analyzed. The temperature field and thermal stress field of 2 1CrMo10 (German grade) material pipe mold were analyzed by finite element analysis software ANSYS The change. The numerical simulation results are in good agreement with the experimental measurements and the damage of the pipe mold in actual production.
