  Parameter-driven Approach to Wheel Flat Modeling in Wheel?rail Impact Dynamics
  Author(s): Ashley Rapp*
  
  Wheel-rail impact dynamics is a critical area of study in railway engineering, especially concerning the interaction between the wheel and rail during train operations. The dynamic behavior of wheel-rail interactions can significantly affect the performance, safety, and longevity of rail systems. One of the most prominent issues in this area is the phenomenon of wheel flats. Wheel flats occur when a section of the wheel surface becomes flattened due to prolonged sliding or braking events. These flats lead to increased impact forces between the wheel and rail, causing undesirable effects such as noise, vibration, and accelerated wear. Understanding and modeling wheel-flat interactions are vital for improving the design and maintenance of rail systems. A parameter-driven methodology for wheel flat modeling offers a promising approach to accurately simulate and analyze the impact dynamic.. Read More»
