| Abstract: | The force-limited vibration test is developed to alleviate the over-testing phenomena in spacecraft vibration test.In lateral direction vibration test,interface moment can be used as an important monitoring and control parameter besides interface force.This paper introduces the principles of force-limited vibration test and describes the methods of estimating the force specifications.Based on the concept of modal effective mass,a strategy of determining moment specification is put forward for lateral direct... |
