Abstract

Interests of increasing the speed of high speed trains, brought more wryness about probable accidents. Whereas passenger wagon CARBODY is considered as a safe compartment for passengers, therefore, great attention should be paid on its design. In this study, a passenger CARBODY (made by Eastern Germany) and its chassis are modeled to simulate crash analysis according to EN 15227 standard. Then, obtained results are used in order to optimize the wagon chassis. This investigation is performed in two steps. In the first step, which consists of simulation of the original wagon model, it is found that due to the lack of efficiency in crash force absorbent, some modifications are needed to consider. In the second step, the original chassis is modified according to modern ones and by implementing honeycomb cores as energy absorbing device, higher absorbed energy is yielded. Also, impact stresses in mid-section of the chassis considerably decreased. The proposed energy absorbing device can be implemented in front end of the chassis to provide a crashworthy structure, however, other investigations such as modal analysis and strength determination should be conducted precede the final structure.
