The analogy between the action of railway rolling stock and powerful vibroseismic sources on the soil mass is shown. A comparison is made between the schemes of loading and the designs of car axle-box wheel pair and unbalanced shaft of source. The expediency is proved for applying the calculation and designing experience, as well as developments in the field of railway transport in creating the powerful vibroseismic sources. 相似文献

以我国某一提速机车为例,建立了计算模型,对其进行非线性临界速度计算,并进行直线非线性运行性能分析和曲线通灶性能分析,得到机车动力学性能对轴箱拉杆定位刚度变化的敏感性,对轴箱拉杆的刚度进行优化,优化后机车的各主要动力学指标,特别是轮轨动态力有明显的降低. 相似文献
