Embodiment Construction
[0017] The present invention proposes a vibrating table for lateral sensitivity calibration of piezoelectric acceleration sensors. The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The vibrating table is composed of a flexible hinge mechanism fixed on a planar two-axis vibration generating device.
[0018] Such as figure 1 Shown is a schematic diagram of the vibration table structure for lateral sensitivity calibration: the flexible hinge mechanism 2 is fixed on the air-floating vibration isolation table 1 of the planar two-axis vibration generating device; the first input platform is respectively fixed on the right end and the lower end corresponding to the flexible hinge mechanism 2 The coupling block 3 and the second input platform coupling block 4; the first input platform coupling block 3 is connected with the first piezoelectric ceramic driver 5 through the threads on it, and the second input pla...
