Abstract

Dimensional analysis is method that used to convert one unit to another unit. It is very important to understand the physical nature of the problem. In the railway vehicle lateral model, dimensional analysis is described as one of the best way to analyze the performance of the railway vehicle in the real and small scale. On the first part of the study, the dynamic modelling of full railway vehicle is used to perform the dimensional analysis in order to observe the acceleration, roll and yaw of the railway vehicle. The full railway vehicle model consist of 17 degree of freedom were described. In particular, one of the objective of the study was to determine the dimensional analysis based on the scaling method. The simulation software, MATLAB Simulink also were studied as one of the medium to analyzed several graph from the simulation work such as body displacement, body acceleration, body yaw angle and body rolling angle. For the second part of the study, the validation between the simulation models were done. To achieve this, the experimental result for the railway vehicle behavior were applied using a simple mechanism to study the pattern and also the performances of both simulation and experiment model. The discussion were including the analysis of the validation and the behavior of the railway vehicle.
