Three-Component Primary Vibration Calibration System at NIM

Chenguang Cai, Zhihua Liu, Ming Yang
  • Abstract:
    A three-component primary vibration calibration system had been set up in National Institute of Metrology, which consists of an air bearing three- component shaker, a sinusoidal three-component control system and a primary three-component vibration measuring system. A motion coupling device based on air bearing force transferring and motion guiding has been developed to simultaneously generate three-component vibration in the three orthogonal coordinates. The rectilinear, circular, and elliptical space motions have been realized by the sinusoidal three-component control algorithm. The three-component measuring system can simultaneously measure the three orthogonal motion quantities based on sine-approximation method.
