Mercedes狡猾的輪胎小把戲被揭露

A trick employed by Mercedes to counter Pirelli’s high mandatory tyre
pressures has emerged.
Mercedes廠隊透過"小把戲"反制Pirelli胎壓設定的手段被揭露了
Earlier, it was suspected that some top teams had found a clever way to
reduce the high minimum tyre pressures once the car was up and running,
thereby boosting laptimes.
早先有人猜測一些頂尖場隊發現了一招很高明的辦法,藉由車子啟動並預熱後去降低
最低胎壓設定值,進而增加圈速。
Auto Motor und Sport has now published photos of a sophisticated device
attached to the four corners ofthe pair of Silver Arrowss prior to the tyres
being fitted on the Baku grid.
Auto Motor und Sport公布了一批在Baku賽道上尚未裝設輪胎前,裝置在Mercedes場隊
車上可疑裝置的照片
Reportedly, the device keeps ultra-high heats in the axle and brakes, so that
when the Pirelli tyre is fitted, it artificially satisfies the minimum tyre
pressure but then rapidly starts to lose that pressure once the car is on
track.
報導指出,該裝置會先將驅動軸及煞車加熱至極高溫,等到Pirelli輪胎裝上後,
輪胎胎壓會被"人工"滿足到最低值,而在車輛跑上賽道後,由於溫度快速降低,
胎壓亦會隨之降低。
The lower the pressure, means there is more surface contact and allows more
flexing of the tire. This provides more grip and helps the tires to warm up
from the inside.
低胎壓意味著有著更多的輪胎接觸面積及更加的輪胎彈性,這方式讓輪胎可以有更佳的
抓地力及更快從內側加熱讓輪胎上升到工作溫度。
At high pressure, the tire is run on a narrower band and the tread becomes
more rigid, thereby heats up faster.
在高胎壓的情形下(這邊應該指的是低胎壓因輪胎工作溫度上升後加熱後胎壓增高),
胎壁變薄進而讓胎面更有剛性,而溫度上升的更快。
Force India technical director Andy Green was quoted as saying a ban of such
practices “would be a good thing. It just costs a lot of money.”
印度威力技術領隊Andy Green對此類似作法被禁止表示"是件好事,但是太花錢了"
