A finite element complex eigenvalue analysis of curve squeal is carried out. Two models for the wheel tread/rail top contact and the wheel flange root/rail gauge corner contact are established. In the both models, the contact between the wheel and rail is simulated with a spring. The friction force is considered as the contact spring force multiplied by a coefficient of friction. The rail is supported by vertical and lateral springs at each sleeper. The simulation result shows that the coefficient of friction, contact point positions and stiffness of the rail support spring all have distinct influences on the curve squeal occurrence. Appropriate stiffness of the rail support spring can suppress or eliminate curve squeal.
