EUWA ES-3.21 Geometrical uniformity and first harmonic point of agricultural wheels
Dear User – this EUWA specification has recently been completely reworked and renamed.
The former version “High Speed Wheels for Agricultural Tractors ≥50 kph” has been canceled and renamed “Geometrical uniformity and first harmonic point of agricultural wheels” as our EUWA Experts are convinced the standard should also be valid for all other agricultural wheels, too. So the standard still provides standardised disc wheels and adjustable wheels for agricultural tractors, radial run out first harmonic high point marking. This marking is used to match-mounting with tyres on wheels to minimise the assembly radial force variation. It has been found that the radial run out has a big influence on the handling of the tractor. Moreover, the amplitude of the vehicle vibration is proportional to the first harmonic of the radial run out of the two bead seats.
