| 中文摘要: |
| 对一个叠层板型堆芯元件实验模型的临界流速进行了理论、数值分析，将该结构视为多层平行梁与整体单梁的对接问题，根据各梁的挠曲线方程及对接处的连续性条件和平衡条件，建立了临界流速和失稳挠曲线方程系数的特征方程，并采用隐式迭代法对其进行数值求解。 |
| 英文摘要: |
| In this paper, the critical flow velocities of an experimental model for the parallel-plate type fuel element assembly are theoretically and numerically analysed. This structure is treated as multi-parallel-beams joined with single-beams. According to the equations of deflection curves of the beams and the conditions on continuity and equilibrium at the joints, an eigen-equation is obtained for solving the critical flow velocities and destabilizing deflection curves, and it is numerically solved with the implicit iteration method. |
