| 摘 要： | 为验证并提高三轴振动试验系统工作平台的谐振频率,进而提高系统的工作频率范围,文章采用有限元软件对平台在自由状态下的模态进行仿真。比较仿真结果与三轴振动试验结果可以看出,对角和对边弯曲频率偏差较小。该结果可为后续设计工作提供相对精确的计算指导。

| Abstract: | To verify and increase the resonant frequency of the platform of a tri-axial vibration test system, and furthermore, to extend the frequency range of the system, the mode of the work table under the free state is simulated using the FEM software, and the simulation results and the tri-axial test results are compared. It is shown that the differences of the bending frequency of the opposite angles or sides are less than 10%. And the result can provide a technical support for the future design. |
