[0002] The exciter is a test device used to stimulate the test object to produce forced vibration in the structural vibration test. At present, when conducting vibration mode analysis tests on mechanical structures, the exciter is usually used to perform a single-point excitation and multi-point response test method. It is often necessary to evenly arrange multiple measuring points in the axial and circumferential directions of the exciter main shaft, and excite each measuring point through the exciter. Then, according to the response of each measuring point of the structural component after the excitation of the exciter, the vibration mode of the structure is analyzed and predicted.
