Development and application of the simulation of dynamic interaction between the multiple vehicles connected high-speed train and the long-distance railway track

Numerical simulations of the vertical dynamic interaction between high-speed trains composed of multiple vehicles and railway tracks are formulated in terms of large-scale, time-dependent linear equations that are repeatedly integrated at each time step. This paper describes improvements in the accuracy of simulations by means of the Hilber-Hughes-Taylor-alpha (HHT-á) method,...
