Torsional Stiffness

本帖最後由 Simon 於 2017-8-7 07:02 編輯

四圍搜集不同車架的torsional stiffness, 意圖找出個 操控 vs Nm/deg 的關係
Caterham Super 7 2000Nm/deg (tubular Space frame)
Mazda MX-5 (1990) - 4880 Nm/deg  (Power plant-Frame )
Mazda MX-5 (later w/ bracing) - 5150 Nm/deg (Power plant-Frame )
Lotus Elise 10,000 Nm/deg (Aluminium Tub)
BMW Z4 e85 14,500Nm/deg
RX7 15000Nm/deg (Power plant-Frame )
Subaru Impreza WRX (2nd-Gen,2002 – 2007 )  (monocoque)  23,000 Nm/deg
Zenos 10000Nm/deg (carbon Space frame)

逢星期日...糕-糕-糕.

無無聊聊又唸
雖然一直都有聽車架剛性一代比一代改良, 又咩咩25%提升torsional stiffness, 又強一倍 點點點.
由這些表與及實戰, 我覺得車架剛性, 必須同車重一齊考慮, 而這兩個因素, 就決定左車架可承受的最大車速.
當超越這個limit, 車身動態會不穩.

除咗安全性之外, torsional stiffness 對 fine running suspension 既影響好大, 因為車架唔夠stiffness 根本不能夠微調避震。

Honda S2000 (1st-Gen, AP1)       7,100
Lotus Elise    10,000
Lotus Elise 111s    11,000
Boxster 986 10000
Boxster 987 16250 (50%less than cayman)
Cayman 987 31,500 Nm/degree is almost as stiff as the 911.
