Ride Diagram: A Tool for Analysis of Vehicle Suspension Settings
This paper proposes a new evaluation method for ride comfort, the ride diagram. The ride diagram is plotted from vehicle accelerations resulting from increased levels of excitation. The idea is to graphically visualize how the ride comfort changes with, for example, road unevenness or speed. The paper further focuses on investigating how fundamental suspension parameters affect the ride diagram shape. The ride diagram has the advantage over the conventional ride measures such as RMS and PSD spectrum that it considers transient events separately. Simulations with a quarter car model show that the ride diagram in several examples is able to separate transients due to nonlinear behaviour, e.g. limited suspension travel, from the stationary vibrations. The effects of choosing a softer suspension with a limited suspension travel are studied; the pros and cons are clearly visualized with the ride diagram. It thus looks promising to utilize the ride diagram for ride comfort evaluation.
