Identification of a dynamic friction model for railway disc brakes

Braking forces occurring during emergency brake applications of passenger trains are generated by disc units. The acting friction depend on the frictional properties between and pad influenced relative velocity, temperatures normal pressure contacting surfaces. In this work a mathematical model is developed which aims to link these influencing variables instantaneous coefficient in order include characteristic behavior calculation longitudinal dynamics railway vehicles. identified use data recorded full-scale dynamometer test rig verified regarding estimation distance.
