VibVue® Pro’s Modal Analysis mode gives engineers and reliability teams a faster, more intuitive way to identify how structures respond dynamically under excitation. In this case, small bore piping was excited using an impact hammer, while VibVue® captured the resulting motion and converted the response into frequency-domain data. Rather than relying only on point sensor measurements, VibVue® enables users to define visual analysis regions across the structure, measure displacement at discrete frequencies, and immediately connect FFT peaks to real physical motion in the video.
This workflow is especially valuable for small bore piping, where vibration-related fatigue can be difficult to diagnose with traditional methods alone. By isolating the dominant natural frequencies at 17.33 Hz and 41.33 Hz, VibVue® makes it possible to see each mode shape independently and understand how the piping is moving at those specific resonant conditions. The result is a clearer path from measurement to diagnosis: engineers can identify problem frequencies, visualize the associated mode shapes, and communicate findings through motion-magnified video that is easy for technical and non-technical stakeholders to understand.
These figures show VibVue® Pro's Modal Analysis mode applied to small bore piping. The videos and FFT data were captured using Modal Analysis recording mode, triggered by the strike of an impact hammer (visible in the raw video). VibVue® generated the FFT spectrum from the color-coded analysis regions shown, each measuring displacement at discrete frequencies. The two most prominent natural frequencies appear as peaks at 17.33 Hz and 41.33 Hz. Filtering each frequency individually reveals its distinct vibration mode, and the corresponding Motion Magnified videos demonstrate each natural frequency in clear, high-fidelity detail.
Together, these results demonstrate how VibVue® Pro can turn complex vibration behavior into clear, actionable visual insight. By combining modal recording, FFT analysis, frequency filtering, and Motion Magnification Video in a single workflow, teams can move quickly from excitation to diagnosis to communication. For applications like small bore piping, where resonance and fatigue risks can have serious reliability implications, VibVue® helps make the invisible motion visible — supporting faster troubleshooting, stronger engineering decisions, and more confident corrective action.
