【Abstract】 Natural frequency of oil-gas vibration damping system on loader work attachments is calculated. Influences of charging pressure of accumulator and load change on system natural frequency are discussed. Kinetic equations are derived according to a simplified single dimensional vibratory model of the system. Through programmed computation, influences of road exciting frequency, accumulator charging pressure and inner diameters of the oil-gas system circuits on damping efficiency of boom amplitude are obtained under full-load and un-load work conditions of loaders.更多还原
