本文论证了主要不同三种类型的偏心压力作用对无缝线路稳定性的影响程度.文中指出了前人计算方法不当之处,作者引用新的计算图式,把轨道作为组合杆件,借用法导方出轨道弯曲微分方程式,假定轨道弯曲变形曲线为正弦曲线,用迦辽金法求解,考虑到轨道的实际联结情况,最后导出了一计算公式.利用所得公式计算与模型轨道试验数值比较结果基本相符.这一新的考虑问题的方法也将为进一步研究轨道局部变形对稳定性影响提供方便.
This paper demonstrates the influence of three main types of eccentric pressure on the stability of the CWR.The article points out the inadequacies of the predecessors’ calculation methods, the author refers to the new calculation scheme, uses the track as the composite rod, Based on the differential equations of the orbital bending of the guide, assuming that the orbital bending deformation curve is a sinusoidal curve, it is solved by the Galerkin method. Finally, a calculation formula is deduced considering the actual connection of the orbit. The results are basically in line with the new method of considering the problem will also be further study of the stability of the local deformation of the orbit to facilitate the impact of stability.
