EnglishA numerical model to predict train induced vibration is presented. The dynamic computation considers mutual interactions invehicle/track coupled systems by means of a finite and discrete elements method. The rail defects and the case of out-of-roundwheels are considered. The dynamic interaction between the wheel-sets and the rail is accomplished by using the non-linearHertzian theory. The strong point of this study consists in the model used to simulate the behaviour of pads. The rail-sleepercontact is assumed extended to an area defined such a contact-zone, rather than a single point assumption which fits better realcase studies. Experimental and numerical validations show how prediction fits well experimental data.
