VIBRATION ON THE PLATFORMS OF VARIOUS UTILITY TRANSPORT VEHICLES AND ON CONTAINERS DURING LOADING AND UNLOADING IN PORT

To determine the mechanical stresses during transportation, vibration and shock measurements were performed on the platforms of various vehicles and 20 ft and 40 ft standard ISO containers. Test data indicate that random vibrations occur on all vehicles in the frequency range between 2 Hz and 500 Hz. In the case of trucks, 68% of the vibration amplitudes of acceleration fall below 1 g, 27% fall between 1 g and 2 g, and 4% between 2 g and 3 g. For semi-trailers and pull trailers, 68% of the vibratory motions have acceleration amplitudes below 1.3 g, 27% between 1.3 g and 1.6 g, and 4% may have amplitudes up to 4 g. The measurements have shown that on the platforms of trucks with air suspension systems 99.7% of all vibration amplitudes do not exceed the level of 0.4 g, on air cushioned trailers 0.7 g.
