Methodology for improvement of turnout performance via crossing shape optimisation

Description

The presented methodology is based on the numerical/experimental analysis of the dynamic behaviour of the train­turnout system and a numerical optimisation technique[1, 2] Firstly, the dynamic interaction between the vehicle and turnout is analysed experimentally using the instrumented crossing (Figure 1). The measured data comprising of the 3­D accelerations of the crossing nose and locations of the impact on the crossing nose (Figure 1) were collected on several turnouts. The measured data confirmed the numerical results presented earlier by the authors that the crossing nose geometry has significant influence on the dynamic forces in the crossing area
