The main purposes of mechanical impedance testing are: 1. Stiffness damping characteristics of materials such as viscoelasticity and composite materials and components such as aircraft, automobile tires and various shock absorbers; 2. Validation of theoretical calculated dynamic properties. Including the origin of cross-linking points (coordinates) of components in dynamic response, stability analysis and vibration control, cross-point mechanical impedance data and vibration mode parameters of the system or component in structural dynamic analysis; 3. Establishing the dynamics of the system or component Mathematical models, including the transfer point (coordinate) of the transfer function (in the time domain
