| 摘 要： | 采用泛函分析法，导出非定常温度场热弹性轴对称问题的线性时空有限元基本方程，并开发了预测轴对称零件承受高温热冲击载荷时热弹性动态应力分布的分析软件。在传热方程中不考虑热耦合项的情况下，建立了轴对称零件承受高温热冲击载荷时的有限元分析理论和离散模型。

| Abstract: | The fundamental equations of thermoelastic finite element method for axisymmetric body were derived by variational analysis, and computer program was developed for predicting the distribution of dynamic thermoelastic stresses in axisymmetric component. The finite element theory and its model were established. The software was employed to analyze the thermoelastic dynamic stresses in the piston with heat shock. |
