| Abstract: | For large Structure, the resonance frequency is very low and the model test system is complex with more test channels. A portable low frequency vibration calibration system for field service is introduced， the system has a frequency range from 0.1Hz to 20Hz and it was used in field calibration service for the model test system of large structures such as launch vehicle etc. Using this calibration system, the testing efficiency and measurement accuracy were significantly improved. |
