It is important to execute a study on reduction of damage of the railway vehicle caused by natural disasters. Authors made a 1 to 10 scale model vehicle for various tests such as a derailment test, an overturning test, which might be difficult to be performed with a full-scale model, and carried out shaking tests under several conditions to find out the amplitude-frequency response of this model vehicle. The results were compared with a half-car vibration models, and we obtained the following conclusions. First, the result of the vertical shaking tests without use of dampers in the model vehicle can be explained well by the often-used half-car model, however it is not the case for the lateral shaking tests. Then the authors proposed an improved half-car model and the model could explain the lateral shaking tests result well. Second, the result of the vertical shaking tests with use of axle dampers in the model vehicle can be explained well in the range up to 10Hz, however it differs from the calculated results in the range above 20Hz. Third, the result of the lateral shaking tests with use of lateral dampers in the model vehicle agrees with the calculated results at least qualitatively, although there are major differences between them at the frequency of 4.5Hz and 6Hz, whose reasons have not been found clearly. Finally, the result of shaking tests with use of all dampers in the model vehicle are about the same as the result with use of axle dampers for vertical shaking tests, and as the result with the use of lateral dampers for lateral shaking tests, respectively.
