Average dynamic radii for five cold (C1-C5) and four hot (H1-H4

Download scientific diagram | Average dynamic radii for five cold (C1-C5) and four hot (H1-H4) WLTCs for each tire (LF, RF, LR, RR), together with table values (308.3 mm) [26] and the front and rear static radii average from before and after a WLTP (305.5 and 308.5 mm, respectively). Indicated in the plots are also average dynamic radii for Phases 1-4 of the WLTC (lines with four smaller markers in series Phase 1 to Phase 4, Phase 1 always lower). As can be seen, all the radii increased in a similar manner throughout the cycles. Also noteworthy is that the hot cycles started at a slightly higher radius than the cold. The maximal difference for each individual wheels was less than 0.3%, which is insignificant with respect to measurement accuracy. from publication: Considerations for Achieving Equivalence between Hub-and Roller-Type Dynamometers for Vehicle Exhaust Emissions | Emissions from vehicles can be measured on the road or in laboratories using dynamom-eters that simulate the forces that a vehicle is subject to while driving on the road.
