THEORETICAL STUDY INTO THE DYNAMICS OF A PASSENGER-COACH WITH UNEVEN LOAD ON THE BODY PIVOTS

TEORETICESKOE ISSLEDOVANIE DINAMIKI PASSAZIRSKOGO VAGONA S NESIMMETRICNOJ NAGRUZKOJ PJATNIKOV KUZOVA

The mathematical model adopted is designed to examine the dynamics of a 4-axle vehicle with 2- level suspension and uneven longitudinal distribution of the weight over the body. Vehicle movement is described by four second-degree differential equations. The dynamic indices of a vehicle with a constant-rigidity central suspension are less favourable than those of a modular-rigidity suspension. Comparison of the dynamic indices of the body to the right of the pivot with the highest load and to that of the pivot with the lowest load shows that the latter's dynamic indices are less favourable. Assessment of the dynamic quality of vehicles with uneven load distribution must consequently be based on the pivot with the lowest load.
