Comparison of models for predicting curve squeal noise
Comparison of models for predicting curve squeal noise
Curve squeal is a highly unpredictable phenomenon due to its random nature. Efforts are made in both the academic and industrial community to analyse curve squeal and identify measures to reduce it. This paper aims to compare two different modelling approaches used in the QuieterRail project to predict curve squeal. The first approach focuses on efficient predictions in the frequency domain, while the second approach evaluates the full system response through a representation of the wheel/rail interaction in the time domain. Models are run with identical input data, corresponding to a resilient tramway wheel circulating on a slab track in a tight curve. Several output variables are compared to investigate the differences in each calculation step of the models: mobilities, friction law, instabilities, wheel vibrations. Despite the differences in formulations, the results are comparable.

Abstract
Curve squeal is a highly unpredictable phenomenon due to its random nature. Efforts are made in both the academic and industrial community to analyse curve squeal and identify measures to reduce it. This paper aims to compare two different modelling approaches used in the QuieterRail project to predict curve squeal. The first approach focuses on efficient predictions in the frequency domain, while the second approach evaluates the full system response through a representation of the wheel/rail interaction in the time domain. Models are run with identical input data, corresponding to a resilient tramway wheel circulating on a slab track in a tight curve. Several output variables are compared to investigate the differences in each calculation step of the models: mobilities, friction law, instabilities, wheel vibrations. Despite the differences in formulations, the results are comparable.
