一、轮轨动力学领域中的研究展望轮轨系统问题的本质系线路与车辆相互作用问题之综合。直接发生在轮轨接触点的限制决定着车轮、钢轨和弹簧悬挂等元件的极限参数,并且在轮轨系统中在用来提高速度和轴载荷等方面存在着相当大的潜力。 1972年在美国召开的线路协会会议上报告了关于高速车辆和重载列车的动力学问题,在许多报告中都指出,为了安全操纵六轴机车,要适当地严格线路标准。为此在某些曲线上可以建议采用较大面积的轨座。
First, the wheel-rail dynamics in the field of research Prospect of the nature of the issue of the system of wheel-rail lines and the interaction of vehicles integrated. The restrictions that directly occur at the wheel-rail contact point determine the limit parameters of the wheel, rail and spring suspension components and there is considerable potential for use in the wheel-rail system to increase speed and axle load. The dynamics of high-speed vehicles and heavy-haul trains were reported at a circuit association meeting held in 1972 in the United States. In many reports, it was pointed out that in order to safely operate six-axle locomotives, the wiring standards should be properly and properly rigorously adopted. For this purpose, a larger area rail seat may be recommended on some curves.
