本文根据Kalker的弹性蠕滑理论,通过研究轮轨接触几何学和动力学关系,用Kane方法建立了北京型内燃机车的多体横向运动模型,提出了一类非线性多自由度系统的分歧解法,并用分歧的观点研究了北京型内燃机车的蛇行,所得理论分析结果与实验相符,为改善北京型内燃机车的运动稳定性提供了理论依据和方法。 According to Kalker’s theory of elastic creep, the multi-body lateral motion model of Beijing diesel locomotive is established by Kane method through the study of wheel-rail contact geometry and dynamics. A new method of bifurcation solution for a class of nonlinear multi- , And studied the hunting of Beijing-type diesel locomotive from different points of view. The theoretical analysis results obtained are in good agreement with those of experiments, which provides a theoretical basis and method for improving the movement stability of Beijing-type diesel locomotives.
