考虑橡胶垫复刚度的钢轨振动力学分析模型

On the Analytical Model of Rail Dynamics Considering the Property of Complex Stiffness of Rubber Pads

本文讨论了轨下橡胶垫的复刚度特性,建立了橡胶垫复刚度的等间距点支承无限长梁模型,并推导出该模型在稳态激振力作用下的解析解。该模型是对轨道力学理论的一个补充。

In this paper, the property of the complex stiffness of rubber pads is discussed. The model of an infinite beam supported by uniformly spaced springs is established, considering the property of complex stiffness of rubber pads. Then its solutions are deduced. The model is a complement to track dynamics.
