Abstract:
To investigate effect on a time-varying harmonic dynamic axle load induced by the change of nonlinear characteristics on suspension dampers installed in the towing car on the dynamic stability of car-trailer combinations, a linear single-track model with a tandem-axle trailer was proposed and an effective axle load was used to quantify the harmonic dynamic axle load. A parameter identification method based on time-frequency analysis was applied in the process, too. Experimental study shows the harmonic effect has a time-varying phenomenon. A simulation method is designed for the purpose of a harmonic force generator to simulate the harmonic effect in road experiments. On this basis, the sensitivity analysis of the influence on the harmonic amplitude or the phase on the system dynamic stability is performed by the simulation. It is preliminarily proved that the proposed theoretical analysis of the harmonic dynamic axle load on the stability effects of car-trailer combinations is reasonable and acceptable.
