Automobile seat suspension with magnetorheological damper

Lord company developed the [8] car seat suspension damper, the damper is a single cylinder type, using compressed nitrogen as compensation, the damping hole annular distribution and electromagnetic coil winding are on the piston, draws out the power line through the piston rod, the damper diameter 4.1cm, two connecting hole center distance is 17.9cm, the stroke of the piston is + 2.9cm, damper consumption of magnetorheological fluid rheological fluid 70cm3, occurred in the piston is 0.3cm3, the input current is 1A when the input power is 5W. The damper using 5 * 106 times without fault, magneto rheological damper, the length of life determines the chemical stability in seal design, material selection and of magnetorheological fluids. Dongguan Jincheng Industrial Co., Ltd. is a research and development, manufacturing, sale of tension control, magnetic damper, as one of the professional manufacturers, the main production: tension device series, magnetic damper series, tension device, magnetic damper, magnetic damper damper, damper, and other goods. Www.www.longdeke.com Damper characteristics of magneto rheological curve obtained experimentally (Fig. 3) and magneto rheological damper is used to control the effect curve of vehicle seat suspension system (Figure 4), suggesting that using controllable damping has excellent damping effect of automobile.
