An ultra-low frequency six-component micro-vibration measurement system comprises a base, a loading disk, four folded beams, strain transducers, dynamic strain gages and a data acquiring and processing system; the four folded beams are evenly distributed in the circumferential direction of the lower surface of the loading disk; each folded beam is perpendicular to every two adjacent folded beams, and one end of each folded beam is fixedly connected between the loading disk and the base; and the strain transducers are pasted to the folded beams, achieve bridge circuit connection through the strain gages and are connected with the data acquiring and processing system. When a micro vibration source vibrates, the strain transducers measure strain generated by the four folded beams and output a voltage signal to the data acquiring and processing system through the strain gages, and vibration characteristics of the micro vibrating source are analyzed by the data acquiring and processing system according to the input voltage signal. The measurement system can accurately measure the disturbance force of the micro vibrating source and is high in measurement accuracy.
