In order to complete the high level vibration test of pipeline in spacecraftheoretical analysis results show that the decisive factor for the pipeline failure is vibration strain, cutting the high frequency region of vibration environment can significantly reduce the vibration magnitudethe difference of the pipeline vibration strain before and after cutting high frequency region respectively by test and finite element method. The results show that under the principle the cut?off frequency higher than the main resonance frequency, the cut?off frequency is chosen to reduce the vibration magnitude, and the vibration strains of the pipeline are not affected. It is acceptable that cutting off the vibration test condition to replace the original vibration test condition the feasibility of pipeline vibration test.
