Abstract It is necessary to know the status of adhesion conditions between wheel and rail for efficient accelerating and decelerating of railroad vehicle. The proper estimation of adhesion conditions and their real-time implementation is considered a challenge for scholars. In this paper, the development of simulation model of extended Kalman filter (EKF) in MATLAB/Simulink is presented to estimate various railway wheelset parameters in different contact conditions of track. Due to concurrent in nature, the Xilinx^® System-on-Chip Zynq Field Programmable Gate Array (FPGA) device is chosen to check the onboard estimation of wheel-rail interaction parameters by using the National Instruments (NI) myRIO^®… More >

Abstract In this paper, four kinds of biocompatible SAMs are used to improve adhesion property and fluorescence reaction property on specimen surfaces. The result of experiment shows that OTS film demonstrates contact angles are all larger than 100 degrees in different immersing time and it reveal the best hydrophobic property after 24 hours. The declination angle experiment demonstrates that the OTS film has best flowing property and same trend of friction coefficient; it indicates that the declination angle experiment can reveal the degree of microchannel adhesion property better than contact angle experiment. It can be found that the OTS film can… More >
