Peculiarities of the Influence of hydraulic vibration damper failures upon the dynamics of a passenger car
When the car is moving along periodic irregularities of the track at a speed when the frequencies of forced and natural oscillations are close in magnitude, large amplitudes of vibrations of the body on the springs may occur, if there are no or small resistance forces in the spring suspension system...

| description | When the car is moving along periodic irregularities of the track at a speed when the frequencies of forced and natural oscillations are close in magnitude, large amplitudes of vibrations of the body on the springs may occur, if there are no or small resistance forces in the spring suspension system. To dampen resonant vibrations, special dampers are introduced into the spring suspension system, which make it possible to reduce the amplitudes and accelerations of the driving motion, and, consequently, to reduce the impact of dynamic forces on the elements of the bogie car with different load capacity (passenger, mail and baggage cars and restaurant cars). Hydraulic vibration dampers of viscous resistance, which, despite the complication of manufacturing, repair and maintenance, are used in the bogies of passenger cars, elastic elements that do not have internal friction are used. Vertical and inclined hydraulic vibration dampers used in wagon bogies have a telescopic piston design. They are easy to operate and have a low weight. |
