In the last years lightweight design has become an essential requirement for modern railway vehicles. Therein, under the aspects of high cost pressure and tight schedules the massive application of CAE methods starting already in the early design phase is a key factor for a successful and efficient product development, as demonstrated by Siemens.

Introduction

Continuously increasing requirements for railway vehicles led to the fact that mass reduction has become an important topic in the last years. Amongst others, increased requirements with regard to safety and comfort, but also with regard to higher passenger capacities, lead to higher masses of the vehicles. On the other side, there is a need for light and economic vehicles with low operating and life cycle costs, in order to fulfill economical and environmental protection issues. Thus, lightweight design has become an essential part, in particular for urban- transport rail vehicles (tramways, metros) typically having a high...

Thanks

The work with regard to structural optimisation has been made in close cooperation with the Institute of Lightweight Design and Structural Biomechanics at TU Vienna. Special thanks go to Professor Helmut J. Böhm for the technical and scientific support and supervision. Furthermore the support of Altair Engineering Inc. with regard to support on the application of structural optimisation tasks is gratefully acknowledged. The content of the present article was presented in November 2016 at the “9. Ranshofener Leichtmetalltage” and published in the corresponding conference proceedings [9].
