Research and Simulation on Numerical 3D Image Simulation of Transportation Track Ice Formation
The ice on the transportion track will affect the speed and stability of the train and increase the safety risk of the train.Therefore,the numerical three-dimensional image simulation of the ice on the transport track are car-ried out.Firstly,the orbital plane is divided into several control bodies,and the falling track and landing position of the water body are obtained according to the continuous phase of the water body and the airflow field in the cur-rent direction.Then,the ice thickness of the track is calculated according to the conservation of water mass and en-ergy.Finally,using Rodrigue matrix transformation strategy and homogeneous coordinate transformation strategy,the dimensionality of data points is unified,and the data points are converted into image element points according to the file conversion format by graphics processor,and the three-dimensional image of ice numerical simulation is constructed.The simulation results show that the method can effectively simulate the three-dimensional numerical image of ice,be immune to common meteorological conditions,and has strong environmental inhibition ability.
