Latest Patents
One of Ruizhe Qiu's key patents is titled "Ballastless track roadbed damage forewarning method and system considering uncertainty." This patent outlines a comprehensive method that includes several steps. The process begins with counting roadbed material parameters and precipitation. Next, a FLAC-PFC model of a ballastless track roadbed is established, and mesoscopic parameters of the roadbed surface layer are calibrated. The method generates a lognormal random field of particle contact friction coefficients, which are assigned to particle contact nodes of the roadbed surface layer. Sampling on the precipitation is performed, and a fluid domain of the roadbed surface layer is adjusted accordingly. The method determines a worst spatial correlation distance in the random field and calculates a damage probability pf of the roadbed surface layer under this worst spatial correlation distance. Alarm information is outputted when pf exceeds an alarm threshold, ensuring timely warnings of potential damage. This innovative method enhances the monitoring of roadbed conditions under dynamic loads, thereby ensuring driving safety.
