Simulation Verification of Indirect Measurement Method for Wheel Rail Force in Urban Rail Transit
In response to the complex installation of traditional wheel rail force direct measurement methods for measuring force on wheelsets,the difficulty of early patch and calibration operations,and the high cost,based on existing relevant research,taking urban rail transit trains as the research object,Simpack dynamics software is used to simulate and verify the theory of wheel rail force indirect measure-ment method.Firstly,the theoretical formula of the wheel rail force measurement method is derived.Using Simpack software,a vehicle track dynamics simulation model is established.Through calculation,the 50％,75％,90％and maximum errors of the lateral force of the straight section wheel axle and the vertical force of the wheel rail under different working conditions are obtained.The results indicate that the indirect measurement method has high measurement accuracy and provides an optional solution to measuring wheel rail forces in urban rail transit.
