| 摘 要： | 针对电动振动台进行整星水平振动试验时垂直方向响应过大这一普遍存在的问题,文章提出了通过设计具有加强筋的加强台面提高滑台抗弯模量,抑制响应。通过有限元方法分析了安装加强台面后对水平滑台、水平滑台与振动花盆组成的振动工装系统、考虑卫星质量影响的振动工装系统等三种工况下模态振型的变化,说明抗弯模量有明显提高。

| Abstract: | It is proposed that a reinforced panel should be used to increase the bending rigidity of the slip table and to reduce the vertical response of the table in the horizontal direction vibration test of spacecraft. In addition, the modal analysis is made using FEA method in three working states: fixing the reinforced panel upon the slip table, the slip table and vibration fixture as a vibrating system, and considering the mass of satellite. |
