Abstract
A device for monitoring healthy status of machinery mounts is provided, which may include a plurality of vibration detectors, a signal acquisition device and a signal processor. The vibration detectors may detect the vibration signals from of a machine device, where the machine device may include a plurality of machinery mounts. The signal acquisition device may receive the vibration signals of the vibration detectors. The signal processor may execute a modal frequency analysis process to analyze the vibration signals of the vibration detectors, and calculate a vibration mode corresponding to the natural frequency of the machinery mounts in current status to serve as the test mode; then, the signal processor may compare the test mode with a reference mode to determine the healthy status of the machinery mounts, where the reference mode is corresponding to the natural frequency of the machinery mounts in the optimized status.
