SUPERIMPOSITION OF VERTICAL AND HORIZONTAL FORCES ON COMMERCIAL VEHICLES

UEBERLAGERUNG VON VERTIKALEN UND HORIZONTALEN KRAEFTEN AN NUTZFAHRZEUGEN

SINCE VERTICAL WHEEL FORCES COMPOSED OF LOAD AT REST AND VIBRATION-INDUCED FLUCTUATIONS ARE WELL KNOWN, THE RESULTING TOTAL FORCES ON THE WHEELS HAVE TO BE DETERMINED TOGETHER WITH THE HORIZONTAL FORCES ON BENDS AND THOSE CAUSED BY ACCELERATING OR BRAKING. A SPATIAL MODEL OF A SEMI TRAILER WITH TWIN AXLES IS BEING EXTENDED. FORCES BETWEEN TYRE AND ROAD ARE BEING DETERMINED FOR THE INDIVIDUAL WHEELS ON SURFACING WITH REGULAR EVENNESS. THE VARIOUS HANDLING CONDITIONS DURING STRAIGHT AHEAD DRIVING AND DRIVING ROUND BENDS ARE BEING CONSIDERED. VARIABLE AXLE CONSTRUCTIONS, PARTICULAR MULTIPLE AXLES, ARE BEING COMPARED.
