| Abstract: | A theoretic investigation on the thermodynamics of the vehicle hydraulic shock absorber is presented.A model of quarter car vehicle suspension system with consideration of the thermo-dynamical characteristics was built.Based on such a model,both the vibration response of the suspension and quantity of heat generated by the hydraulic shock(absorber) was computed.The relations between the thermo-dynamical characteristics of the damper and the suspension(system) parameters,including sprung mass,unsprung mass,suspension stiffness and tire stiffness were worked out.And the effect of operation conditions on damper thermodynamics,including vehicle speed and road irregularity were also(investigated).The research result will be very helpful for the design and the matching of shock absorber,and are also basis for intending research. |
