| 摘 要： | 用有限元法求解非定常温度场时,如果取较小的时间步长,常会出现不合理的数值“跳跃”现象.本文采用修正后的 Fourier 定律和集中质量热容矩阵法给出了热冲击温度场的有限元基本方程.并对轴对称物体的热冲击温度场进行了有限元分析.

| Abstract: | When in solving nonstationary temperature fields by FEM,if some smaller steps are taken,unreasonable numerical fluctuations often occur.In order to settle these problems,the basic equa- tions of FEM,with which the numerical analysis done on an axial-symetric temperature fields caused by thermal shock,are given in the paper by means of modified Fourier's Law and the concentrated capacity matrix method. |
