Abstract

The growing traffic demands in railway systems require innovative sleeper designs. This creates the need for efficient simulation methods to support early-stage design and optimization tasks. In this paper, a modular and computationally efficient simulation framework for analysing the dynamic behaviour of railway sleepers is developed. The framework provides calculation modules with Euler-Bernoulli beams as well as multibody dynamics approaches. The calculation times and result qualities are compared. Furthermore, the framework is applied to compare conventional sleepers with innovative ones, focusing on load distribution, dynamic response, and local pressure behaviour. It is shown that the desired quantities can be calculated within seconds while maintaining sufficient accuracy for a wide range of applications.
