Analysis of the Formation Mechanism of Subway Curve Squeal Noise Considering Temperature and Humidity Change

doi:10.3901/JME.2025.06.217

Abstract

Abstract: Metro vehicles are prone to curve squeal noise in small radius curves. The decreasing friction mechanism between wheel and rail is considered to be one of the possible reasons for curve squeal noise. However, under long-term service conditions, the creep conditions between wheel and rail with different temperatures and humidity are different, and the wheel-rail contact state is significantly affected by environmental factors. The mechanism of the influence of the environment on curve squeal noise needs to be further explored. To explore the influence of the environment on the curve whistle, a theoretical model of subway curve whistle noise considering temperature and humidity changes is established. Based on the analysis of the curve passing behavior of the train, the dominant mode that may cause the curve squealing noise of the wheel is found by using the measured noise data, and the relationship between the axial vibration mode of the wheel that produces the curve squealing and the squealing noise is pointed out. Through the investigation of the annual temperature and humidity changes in Shanghai, the influence of temperature and humidity changes on the lateral vibration of wheels and the curve squeal noise is analyzed, and the causes of the curve squeal noise are discussed. The results show that the descending friction condition between wheel and rail is necessary for transverse self-excited vibration of the wheel. When the lateral vibration velocity of the wheel is close to the creep velocity, the periodic lateral force mutation occurs. The asymmetry of the system's periodic input power causes the system's energy dissipation. The excitation of the axial mode of the wheel is the possible reason for the curve whistling. Compared with high temperature and humidity in summer, low temperature and dry winter are more prone to curve squeal noise, and the squealing noise is sharper. To avoid environmental pollution caused by squealing noise, it is recommended to pay more attention to the maintenance of wheel-rail in winter. The work of this study has a certain reference value for understanding the causes of rail vehicle whining and further suppressing the whining noise.
