本文利用文献大量有限元计算数值结果,分析了Timoshenko理论公式的适用范围和误差大小,并在不同D/H之比范围内,导出了Timoshenko公式的两个修正公式。为压差加载激光全息无损检测的可检范围、设备和工艺参数的选用提供具有良好精度的计算公式。
In this paper, a large number of finite element methods are used to calculate the numerical results. The applicable range and error of Timoshenko’s theoretical formula are analyzed. Two modified formulas of Timoshenko’s formula are deduced at different D / H ratios. Provide a good accuracy of the formula for the checkable range of laser holographic non-destructive testing of pressure-loaded lasers, the selection of equipment and process parameters.
