Abstract：Combined with the suspension motion transfer equation, the energydissipative power was derived based on road roughness statistical characteristics. A linear relationship of road level, vehicle speed and energydissipative power of suspension was obtained. According to the numerical analysis, the numerical relationship between energydissipative power and road level was achieved under certain conditions. An energydissipative factor was put forward based on the suspension parameters. Within the selected range of suspension parameters, a linear relationship between wheel stiffness and energydissipative factor was obtained through the sensitivity analysis of the energydissipative factor. The unsprung mass has negligible impact on the energydissipative factor, while the sprung mass, damping and suspension stiffness have no impact on the energydissipative factor. The theoretical model of energydissipative power was concluded.
