To achieve microvibration protection of precision machines, it is very important that microvibration sensitivities of these machines be measurable, but no measuring method has been developed. Conventional vibration testing devices cannot generate microvibrational waves under 10 Gal. The authors have developed a microvibration testing device that employs active control technologies. The trial device, which comprises pneumatic-type actuators and a newly developed DSP (Digital Signal Processor) controller, successfully generates sinusoidal microvibrational waves at the magnitude of 0.1 Gal on a vibrating floor. These waves were realized with a noise rate of less than 10%. This paper outlines the developed system, and some experimental results are shown.
