Multi-directional wide-angle continuous scanning vibration measurement auxiliary device based on single point laser vibrometer

摘要

PROBLEM TO BE SOLVED: To provide a multi-direction wide-angle continuous scanning vibration measurement auxiliary device based on a single point laser vibrometer. A multi-direction wide-angle continuous scanning vibration measurement auxiliary device based on a single-point laser vibrometer, wherein an X-axis rotary motor (15) is provided on a stand (2), and the X-axis rotary motor (15) is Driving the rotation of the outer frame ring drive wheel of the set causes the outer frame ring (18) to rotate within the outer frame ring support groove (16); the outer frame ring (18) is a member coupling. The Z-axis rotary motor (21) is fixed to the rod (19), and the Z-axis rotary motor (21) is attached to the central portion of the member connecting rod (19). (19) It is driven to rotate around; the bottom of the member connecting rod (19) is fixed to the reflector support ring (23); and the cube reflector (31) is provided at the central portion of the cube reflector rotation shaft (27). The Y-axis rotation motor (28) is fixed to the other side of the inner frame rotation ring (25). The fixed beam can be projected in multiple directions, and when the laser Doppler vibrometer is not adjusted, the laser can be projected at an arbitrary position that the user wants to measure, and the measurement becomes very easy.
