摘要： A precision tilting platform used for static calibration of seismometers includes a base, a worktable, a rotary part, a driving part, a measuring part and supporting frames. The rotary part includes a shaft, a driving arm, a rotary table and a clump weight. The driving part includes 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 a signal of zero position when the worktable is horizontal. The sliding table contacts the driving arm. When the linear motor is moving forward, the rotary part rotates toward the positive direction. When the linear motor is moving backward, the rotary part rotates toward the negative direction under gravity of the clump weight. The measuring part includes a laser interferometer and a reflector to obtain the tilting angle of the worktable.

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.
摘要翻译： 用于地震仪静态校准的精密倾斜平台由基座，工作台，旋转部件，驱动部件，测量部件和支撑架组成。 旋转部分由轴，驱动臂，旋转台和重量组成。 轴固定在左右支撑框架上。 驱动部件和组块重量组装在驱动臂的两侧。 驱动部分由线性电动机，滑动台，一对直线导轨和滑块以及光栅尺组成。 光栅尺的读数头与基座固定，当工作台水平时，发出零位信号。 滑动台与驱动臂紧密接触。 当线性马达向前移动时，旋转部分被滑动台推动并向正方向旋转。 当线性电动机向后移动时，由于重量的重力，滑动台被向后拉，旋转部分朝向负方向旋转。 测量部分由激光干涉仪和将激光束反射回激光干涉仪的反射器组成，以获得反射器安装在其上的工作台的倾斜角度。 本发明具有定位精度高，传输效率高，应用广泛的优点。
