Abstract

The vibration characteristics of the shock absorber in the dynamic condition differ from the “quasi-static” characteristics. For analysis of the processes occurring in the shock absorber, measurements were carried out on a universal servo-hydraulic test rig. The principle arrangement is described. A twin-tube shock absorber was prepared with acceleration, oil pressure and valve lift sensors. To understand this changing of the operating characteristics the analysis of the vibration system “shock absorber” was carried out. The rote cause for damping force irregularities was found. With knowledge of the valve operating characteristics in conjunction with the internal pressure characteristics, effective optimization strategies can be pursued.
