Truck cabin vibration

The vibrations of the cabin walls of a light weight truck cabin have been analyzed with this technique. The cabin was positioned on the test bench and excited with a shaker. The resonance frequencies have been determined with accelerometers at few measuring points. In this application, the PulsESPI measurement served simply for display of the vibration mode shape. Therefore, the interesting frequencies could directly be excited with the shaker and the PulsESPI system could directly be triggered to the accelerometer signal.

The measured phase maps and the corresponding amplitude maps of the rear wall are displayed for each resonance frequency.

Similarly, the vibrations of the left and right doors have been analyzed with the PulsESPI system. The complete measurement cycle of one side of the cabin wall can be carried out within 1 hour time.
