Simulation Analysis of Wheel and Track Based on Floating Slab Track

Computing and analysing the relationship between floating slab track and vibration and noise can offer reference to engineering.Based on the model of wheel and track vibration considering its irregularity,the finite element model was established by ANSYS.Transient response was simulated under the train dynamic loading by means of Newmark time integration.Analysis the different vibration isolator parameter can figure out the effect to vibration and noise.Floating track slab system is an effective anti vibration and noise,there are different effect between stiffness and damping to control vibration and noise.
