Application of the Aerodynamic Numerical Simulation Method in Designing Railway Freight Cars for Granular Cargos
When a railway freight car carrying granular cargo is running,the natural wind and the air flow formed by the running car will disturb the cargo and cause some loss of cargo and pollution to the environment.The simulation analysis is carried out on the air flow field of train by using the aerodynamic numerical simulation methocl of the train,optimizing the car design solution through analysis,statistics and evaluation of the movement and spreading rate of the granular cargo under the influence of the air flow field in order to determine reasonable and effective structural design and measures to meet the requirements of design indexes.Compared with the vehicle field test involving high cost and long duration,this numerical simulation calculation method is an ideal,economical and practical aided design method in terms of theoretical guidance and optimized comparison and selection of technical solutions.
