本文仅就影响列车起动阻力值的一些主要因素——油类、外界空气温度、停车时间和车辆荷载,并结合实际调查所得有关列车起动情况及操纵方式对目前采用最小列车起动阻力值为4公斤/吨的问题作了初步研讨,并建议改为3公斤/吨。

In this paper the railway track is considered as a double elastic system of both rails and sleepers and the vibration is described in detail with two partial differential equa tions. The author deduces an analytical solution on the steady static vibration of tracks under concentrated sinusoidal impulse load and constant speed. At the same time a detailed calculation is given, under moving load,on the moving speed of load and the influence on the steady state vibration of tracks with various track parameters.

本文将铁路轨道看作由钢轨和轨枕组成的双层弹性系统,用两个偏微分方程联立描述其振动。 作者推导了集中正弦脉冲荷载及等速运行荷载下的轨道稳态振动的解析解,并且详细计算了运行荷载下,荷载运行速度及各种轨道参数对轨道稳态振动的影响。

The wheel-rail interaction, in nature, is nothing but a problem of contact stress produced in a body subjected to repeated loads. A rational strength criterion of such a problem can be found only by a shakedown analysis on the theory of plasticity. In this paper, after the introduction of Hertz's elastic solution of the wheel-contact stress, a shakedown analysis is made according to Melan's rule and the new criterion for the wheel-rail strength design, i.e.( τ_(xz)~2 + τ_(yz)~2)_(max)≤k~2, proposed as well....

The wheel-rail interaction, in nature, is nothing but a problem of contact stress produced in a body subjected to repeated loads. A rational strength criterion of such a problem can be found only by a shakedown analysis on the theory of plasticity. In this paper, after the introduction of Hertz's elastic solution of the wheel-contact stress, a shakedown analysis is made according to Melan's rule and the new criterion for the wheel-rail strength design, i.e.( τ_(xz)~2 + τ_(yz)~2)_(max)≤k~2, proposed as well. It is shown that the maximum axial load determined by the new criterion is much larger than that by the elastic solution. Illustrative examlpes reveal the maximum axial load can be increased by 64%.

轮轨的相互作用实际上是反复荷载作用下的接触应力问题。只有运用塑性理论的安定性分析才能找到合理的强度判据。本文在论述轮轨接触应力的Hertz弹性解后,根据Melan定理进行了安定性分析,并提出了轮轨强度设计的新判据,即(τ_(xz)~2+τ_(yz)~2)_(max)≤k~2。结果表明,新判据大大地提高了根据弹性解所确定的最大轴重。算例指出,最大轴重比弹性解提高64%左右。
