ランダム振動試験における加速度リミットレベルの設定法に関する検討

摘要

Vibration tests of space hardware are often over tested compare to the flight environment due to the mountingimpedance differences in flight versus test. Several limit methods are used to prevent the over testing of satellite systemvibration test.In this study, we propose a method with simple model to estimate the acceleration limit value which does not depend onthe complex CLA (Coupled Load Analysis) model. This method is abailable for random vibration test of components of asatellite. The basic study of the proposed method with several experiment results are discussed in this report.
