This paper deals with the development of a numericalmodel, based on the Finite Element (FE) theory for the prediction of the squeal\nfrequency of a railway disc brake.The analytical background has been discussed and presented, as well as the most efficient methods\nfor evaluating the system stability; the attention has been paid particularly to the complex eigenvalues method, which has been\nadopted within this paper to investigate the railway disc brake system. Numerical results have been compared with measurements\nfromexperimental tests in order to validate the proposed numerical approach. At the end of this work, a sensitivity analysis, aimed\nat understanding the effects of some physical parameters influencing the stability of the brake system and the squeal propensity,\nhas been carried out.
