| 摘要: |
| 为分析圆锥壳的热应力问题，建立了圆锥壳热弹性问题的基本微分方程，运用分布参数传递函数方法求解了受温度场作用圆锥壳的位移与热应力。计算结果表明，解析解与有限元解吻合良好。该方法可以对不同边界条件下圆锥壳的热变形和热应力问题进行分析，还可以推广到旋转壳母线形状为曲线的情况。 |

| Abstract: |
| To analyze the thermal stress problem of thin conical shells, the basic thermoelastic differential equations of thin conical shells are established; the displacement and thermal stress in conical shells under temperature field are analyzed, using the distributed transfer function method. The calculation results show that the solution obtained by the distributed transfer function method matches well with the solution of the finite element method. The proposed method is able to analyze the thermal stress in thin conical shells with arbitrary boundary conditions and other loads; besides it can be further extended to the case of revolution shells with curvilinear generatrix. |
