Study on Dynamic Characteristics of High Speed Projectile Impacting Concrete Target

Simulation of High-velocity Penetration for Rigid Projectile into Plain Concrete Target using Discrete Element Method

Study on different solutions to reduce the dynamic impacts in transition zones for high-speed rail

One of the most important factors influencing the track maintenance is the transitions between parts of the track with different vertical stiffness. The dynamic...

Simulation of dynamic response of projectile and granular target

In the present study, the three-dimensional elastic discrete element method (DEM) and the elastic finite element method (FEM) analysis were, respectively, applied to the randomly distributed identical spheres as a granular target and to the cylindrical projectiles in order to clarify dynamic response during penetration. In the target, it was found that highly densified region was formed just ah...

Study on Braking Panels in High Speed Trains Using CFD

With speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. In this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. The results of simulations are carried out with the computational fluid dyna...
