The Vehicle Subsystem
Today there is a general trend towards increased train speeds (see also SECTION II). However, higher speeds usually generate increased forces and accelerations on the vehicle and subsequently forces on the track. This leads to requirements for lighter car bodies, which reduce the impact between wheels and rails. However, lowering the car-body weight also means a reduction of the stiffness of the vehicle structure, which results in lower natural frequencies. This increases the risk of resonance vibrations, which negatively affects ride comfort. Car body vibrations can be reduced either by focussing on the structural stiffness of the system or by optimizing the damping components ([56]).
