Abstract

The high-speed load model (HSLM-A) was developed more than 20 years ago. Since 1999, the vehicle technology and bridge design have developed accordingly. So new vehicle types, which are not always covered by the standardized load model, must be examined additionally. Within this paper the need of a new dynamic load model for dynamic analysis of railway bridges will be demonstrated. Investigations were done based on currently running passenger trains, which results into a train database of about 3200 train configurations of operating trains within central Europe. To cover possible future train configurations, fictitious parameterized train sets were created. Two different methods the train signature and FEM- computations on a large-scale set of bridges demonstrated that the existing HSLM-Model does not cover real operating passenger trains. 510 relevant trains could be identified as relevant and define a refence line for operating trains. On top 67 fictitious resonance trains were found on the variation of different geometric train vehicle parameters which could be a worst-case scenario All this demonstrates, the need for a new high-speed load model.
