试验结果表明，球锥贮箱液体晃动可能与卫星章动共振，而使章动发散时间常数剧烈下降。
The test results show that, the liquid sloshing in sphere-cone tanks may resonate with satellite nutation, and nutating divergent time constant will be shapoly reduced.
由模态分析看出，筛箱固有频率和工作频率不重合，因此在工作中不会产生共振。
According to the modal analysis, the natural frequency is not coincident to working frequency, so there would be no resonance occur during work.
在选定模型箱结构的外形与构造时，借助有限元分析论证了可不与模型土发生共振的箱体构造；
It is proved by FEM analysis that the proposed shape and structure of the test box can avoid resonance with the model soil.
