SUSPENSION ENGINEERING / 09

Rough Road Tuner

Calm the chassis. Keep the tire planted.

Spring rate · kN/m Damper · N·s/m Test speed · m/s

Tune the spring, damper and test speed. Travel the fixed road in 8 seconds; keep body RMS acceleration, suspension travel and tire lift below mission limits. Compare repeated runs on exactly the same deterministic road.

Model, controls & source

Genuine LABSUS deterministic ISO 8608 road-spectrum synthesis (MIT) drives a reduced two-degree-of-freedom quarter-car spring/damper model. Vehicle mass 250 kg sprung, 35 kg unsprung, tire stiffness 180 kN/m. Educational model; no real vehicle tuning advice.
