One of the most important results of running test of railway cars is that amplitude or acceleration of vibration ξ has complete reproducibility and is a function of the running speed V, the character of the car K and the bed parameter x ; that is, ξ=f (V, K, x). Treating the vibration charts, we cannot infer the vibration characteristics of cars, such as the relation between ξ and V, by means of the incomplete scatter diagrams, which have been used as a conventional method. So the writer plots the complete scatter diagrams of ξ to V by all the waves of vibration charts, and obtaining the curves of regression we can consider the curves as the running characteristics of cars. Requiring the curves of cars by the above method, the writer find out that the resonance speeds are explained well by the natural periods obtained by means of Part 1.
