What is Modal Analysis?
Hey there, today we are diving into the captivating realm of Modal. At its core, Modal Analysis
is the studies of dynamic behaviour. It helps us understanding how structures groove, sway, and
respond to external forces. Think of modes as the unique flavors that give structures their
distinct personality, much like colors or sizes define objects. Modal Analysis takes centre stage
in monitoring the vibration of structures like bridges, buildings, and aircraft. In the lab,
engineers use specialized equipment to conduct structural experiments. Which helps to improve
designs and production processes. In an industrial production environment, modal analysis is
excellently suited for quality assurance and helps to cut costs during the acceptance process. In
maintenance and repair Modal Analysis is used on aging infrastructure or machinery, engineers
can detect hidden flaws or weaknesses before they escalate into costly disasters. This proactive
approach allows for targeted repairs and maintenance, extending the lifespan of critical assets
and ensuring they operate at peak performance. Whether it's detecting hairline fractures in a
bridge or identifying worn-out components in industrial machinery, Modal Analysis plays a
vital role in keeping our world running smoothly and safely.

WaveCam - Motion Magnification: #motorcycle
มุมมอง 338 หลายเดือนก่อน
We have measured a #motorbike with impulse excitation. And we have to admit, never before has a #VibrationTest been completed faster. And the most amazing thing: The results are extremely precise compared to classical sensor systems. Have you ever thought that you can do something like this with a high speed camera? The possibilities are endless. Write us what your #application is, maybe we can...

Berlin Science Lab: Welcome Trailer
มุมมอง 250ปีที่แล้ว
Hey there, my name is Jakob and I'm part of the team at GFaI in Berlin. We are computer science researchers and our work focuses on structural dynamics and pattern recognition. We look at everything from the vibrations of everyday objects to the movement of larger structures and we use all kinds of cool technology like AI and advanced math to make sense of it all. Our goal is to make our work a...
WaveHit MAX Christmas Special - o christmas tree

The WaveHit MAX guarantees a fully automatic, reproducible and high precision excitation of a test object without any double hits. The integrated signal processing of the WaveHit MAX offers new advantages compared to the partially automated ones like: fully automatic single hit excitation, automatic search for user defined impact force, automatic zero-point search, validation of the impact for ...
Chladni Plate: Visualize #Sound and #Vibration with sand
มุมมอง 2.6Kปีที่แล้ว
Ever heard of Ernst Chladni? No? But maybe you've seen the forms named after him. You can definitely call his research fundamental to the #NVH field. Even Napoleon said about him, "This man makes you see the sounds." We have slightly modified his experiments. In ours, an electromagnetic shaker excites a steel plate on which we have spread colored sand. When we set the shaker to exactly a natura...

WaveSim - Combines vibration simulation and measurement: #Car rim
มุมมอง 136ปีที่แล้ว
In this application, we scanned a car rim with an #Intel real sense camera and then simulated it with #WaveSim software. Thereby, all essential modes could be calculated in comparison to the simulation from the manufacturer's CAD model. Vibration simulation has never been faster and more intuitive, yet presize. #WaveSim supports you with little effort and without requiring expert knowledge in v...

    Thanks for posting - interesting video Jacob. Is this technology able to "see" vibrations of the bridge or the belly of the instruments, or are they too small?
