双挂列车的模型建立与稳定性分析
Model establishment and stability analysis of double road train
摘要
Abstract
This paper builds a double road train(A-double)model and analyzes the influence of mass and radius of gyration on the stability of double road trains.Lagrange equation is employed to build a five-degree-of-freedom single-track dynamic model for double road trains.Then,a mathematical simulation model is built and compared with TruckSim model to verify the effectiveness of the simulation model.The stability evaluation index of the double trailer train is discussed and the overall driving stability of the double trailer train is assessed with the maximum yaw rate and its rear amplification factor in the three vehicle units.An analysis of the influence of parameters on double road trains shows an increase in the mass or turning radius of the semi-trailer leads to a decrease in the driving stability of the three vehicle units whereas increasing its mass with its moment of inertia unchanged produces the opposite effect;an increase in the mass and turning radius of a center-axle trailer,or maintaining its moment of inertia constant results in a decrease in the riding stability of both trailers and an improvement in the stability of the tractor;the mass and turning radius of two trailers have a greater impact on the stability of the trailer than the tractor;applying the same load to a centre-axle trailer is more likely to cause a decrease in overall riding stability of the double road train than to a semi-trailer.关键词
