Exciters can be used for model excitation tests on machine tools, bridges, dams and other structures. Through model testing, dynamic parameters such as dynamic stiffness, damping coefficient and natural frequency of the test object can be measured, providing indispensable data for design.

Modal analysis for the excitation method of the exciter, combined with impedance heads to record the excitation force signal and structural response acceleration signal, and obtain the structural modal parameters through data post-processing. According to different experimental requirements, selecting exciters with different thrust and cooperating with signal sources and power amplifiers, can effectively excite the structure in various ways such as fixed frequency and sweep frequency.
