Can a tire accept high suitcase too a depression rolling resistance? I beak alongside Michelin at the Shell Eco-marathon Americas to abide by out! When it comes to designing for efficiency, at that spot are 5 major forces which a vehicle needs to overcome: aerodynamics, internal friction, gravity, inertia, too finally, rolling resistance.
Rolling resistance is the unloose energy consumed yesteryear a tire every bit it travels over a specific distance. Energy is lost every bit estrus when the tire deforms on the road, creating the contact patch, too and thus returns to its master solid position down every bit the tire continues to rotate. How much unloose energy is lost is a number of the tire’s hysteresis.
The finish is to trim down rolling resistance field yet maintaining grip.
Silica compounds, outset invented yesteryear Michelin, accept depression unloose energy losses inwards the depression frequency range, important depression rolling resistance, but high unloose energy losses inwards the high frequency range, important they accept high grip. As a result, it genuinely is possible to accept tires which demonstrate depression rolling resistance too yet all the field high levels of grip. Michelin is 1 of many partners that plays an of import exercise inwards the Shell Eco-marathon, dedicating a manufacturing found for 2 days per twelvemonth only for making the ultra-low rolling resistance tires used yesteryear the teams.
The Shell Eco-Marathon is a contest where students some the footing compete to design, build, too examination vehicles alongside the finish of creating a vehicle that goes the furthest distance using every bit niggling unloose energy every bit possible. Big thank you lot to Shell for having me out to the lawsuit too sponsoring this video!! Check out the Shell media outlets below:
