| Abstract: | Mechanical impedance is a concentrated parameter representation of the mechanical system characteristics, which is an important tool to solve the mechanical system coupling problem. The existing mechanical impedance measurement methods were using exciter or impact testing method, but have their own limitations. In this paper, an improved impact method is proposed to measure the driving point impedance. The feasibility of this method is proved by the experimental comparison. It is proved that this method can obtain the driving point impedance of the structure quickly and accurately, and it has engineering practicability. |
