Abstract

Abstract:

The evident frame flexibility of the commercial vehicle will affect the handling stability and ride comfort of the whole vehicle， especially during resonance when the frame flexibility amplifies the impact on the vehicle’s motion quality. The property-based modeling technical route is adopted in this paper to simulate the frame motion of the tractor-semitrailer in real time. Firstly， the movement of the frame is decoupled into low-frequency rigid movement and high-frequency flexible movement according to the frequency domain. Then a rigid frame module based on multi-body dynamics and a flexible frame module based on the modal synthesis method is modularly built. Afterward， the results of the two modules are superimposed to form a rigid-flexible combining frame model. Finally， the frame model is embedded into the tractor 89DOF-semitrailer 73DOF vehicle model to conduct simulation on a certain commercial vehicle. The model's effectiveness is verified by comparing it with the field test results of an actual vehicle.

Key words: frame, rigid-flexible combination, tractor-semitrailer, property, dynamic model
