QUANTIFICATION OF WHEEL LOAD DYNAMICS FOR SINGLE, DOUBLE AND TRIPLE AXLES DEPENDING ON THE SPRINGING AND SHOCK ABSORBER SYSTEM OF THE VEHICLE

QUANTIFIZIERUNG DER RADIASTDYNAMIK BEI EINFACH-, DOPPEL- UND DREIFACHACHSEN IN ABHAENGIGKEIT VOM FEDERUNGS- UND DAEMPFUNGSSYSTEM DES FAHRZEUGS

In the context of a multi-part research project on the effect of commercial vehicle design on road loading, the aim of the investigations explained in detail was to obtain information on the possible scatter of actual road loading by the spring axle systems of heavy commercial vehicles (vertical additional dynamic loads) by systematic measurements on roads. 8 ton trailer axles with trapezoidal leaf springs, with parabolic leaf springs (single and twin tires) and 10 ton trailer axles with parabolic leaf springs, with air springs and hydraulic shock absorbers, with tuned springs (with and without hydraulic shock absorbers) and with normal tuned springs (with and without hydraulic shock absorbers) were examined. Data are given on the execution of the experiments (experimental vehicle, measured section, extent of experiment), the processing and evaluation of the measured values and the results for single, double and triple axles. The time course of additional dynamic load, the effect of driving speed, distribution of vertical forces along the road track, comparison of springing systems, effect of tires, frequency analysis and motorway driving were determined. The "shock factors" measured on different road surfaces are mentioned.
