Abstract

The application provides a vibration noise characteristic detection device and method for an aviation warning ball. The device comprises a support frame, a ground wire suspended on the support frame, a counterweight module arranged on the ground wire and spaced from the suspended end of the ground wire, and a vibration generation module connected with the ground wire for applying vibration excitation to the ground wire to simulate the vibration working condition of the ground wire in an actual operating environment. The application applies sweep frequency vibration excitation to the ground wire through the vibration generation module to simulate the vibration working condition of the ground wire in the actual operating environment, simulates the mass distribution of the suspended object on the ground wire through the counterweight module, and synchronously collects the noise signal of the aviation warning ball through the noise measurement module to obtain multi-dimensional acoustic parameters such as the sound pressure level, spectral characteristics and time-frequency characteristics of the aviation warning ball, thereby solving the problem that the vibration noise mechanism of the aviation warning ball is unknown, the acoustic performance is difficult to evaluate, and scientific basis cannot be provided for structural optimization design due to the lack of systematic detection means for the vibration noise characteristics of the aviation warning ball in the prior art.
