WebAiM’s suspension analysis in its Race Studio 2 software package automatically generates suspension velocity histograms from position data. In working with the histograms, we must set a transition point between low-speed and high-speed damping. In both examples here they are set at 100mm/s of wheel velocity; this value is not cast in stone ... WebIn mathematical terms, we're talking about taking the derivative of the displacement over time to calculate the velocity. 00:39: In practical terms, we're taking the slope or difference between two measured damper positions to calculate the velocity. 00:47: The calculation being the change in position over a known time step. 00:53
