摘要： A precision tilting platform used for static calibration of seismometers is composed of a base, a worktable, a rotary part, a driving part, a measuring part and supporting frames. The rotary part is composed of a shaft, a driving arm, a rotary table and a clump weight. The shaft is fixed on the left and right supporting frames. The driving part and clump weight are assembled beside the two sides of the driving arm. The driving part is composed of a linear motor, a sliding table, a pair of linear guides and sliders and a grating scale. The readhead of the grating scale is fixed with the base and sends out the signal of zero position when the worktable is horizontal. The sliding table is closely contacted to the driving arm. When the linear motor is moving forward, the rotary part is pushed by the sliding table and rotates toward the positive direction. When the linear motor is moving backward, the sliding table is pulled backward and the rotary part rotates toward the negative direction because of the gravity of the clump weight. The measuring part is composed of a laser interferometer and a reflector that reflects the laser beam back to the laser interferometer to obtain the tilting angle of the worktable, on which the reflector is mounted. The present invention has the advantage of high positioning accuracy, high transmission efficiency and wide application.
