Most of the suspension systems of modern vehicles use oil dampers. The working principle, including those designed by Yonggui Electric, is when there is relative motion between the bogieand the axle box (or the body of vehicle and the bogie) duetovibration. The piston in the damper moves up and down, The oil in the working cylinder flows from one chamber to the other through the orifice, At this time, the friction between the valve systemand the oil and the internal friction between the oil molecules produce damping force on the vibration, The vibration of the vehicle is suppressed, Vibration energyisconvertedinto heat energy, Radiate into the atmospher.
