A damping measurement system based on the LabVIEff graphical programming language utilizes the cross-correlation of received velocity vibration signals and excitation signals to obtain the specimen's velocity impact response, which is then transformed into the frequency domain to yield the velocity frequency response function. This system can determine the resonance peaks within a frequency range and the half-power bandwidth through a single measurement, with the program automatically selecting resonant peaks and calculating the damping loss factor. Compared to traditional methods, it offers high measurement accuracy and speed, as well as good openness. Technical specifications include: 1) Using swept frequency signals to excite the specimen for obtaining the velocity frequency response curve, which allows determination of the clamping position of the specimen and whether the thickness of the damping coating is appropriate based on the morphology of each resonance peak. 2) Simple operation, capable of generating reports from relevant data obtained in one measurement, offering high measurement precision and efficiency. 3) The program behind the front panel can be easily modified by adding input controls for entering the dimensions of the specimen. Thickness, mass and other parameters can determine the complex bending modulus and damping loss factor of the damping material. Application fields: Noise and vibration control damping material design; Optimization and design of damping coatings on metal thin plates.
