※ 引述《twelvethflor (渴了)》之銘言:
: 由於沒有撞測,所以就是一般大眾心裡的主觀意見啦!
: 以下均是指新款
: 1.ALTIS
: 2.ELANTRA
: 3.FOCUS 5D
: 4.GRAND LANCER
: 5.KICK
: 我的既有主觀意見是,最硬是焦點 最軟是神A。
: 其他就不知道了,想問問大家,最軟到最硬的排列為何?
: 這樣我評估會資料會完整一點,謝謝大家
在台灣只有法規撞測,以上5台能上市都過法規撞測
至於說送去國外測啥的,"送測"就宣傳效果居多
台灣的問題又不是沒實驗室有能力測,而是沒NCAP第三方幫你評鑑
送測完自己打分數,這種裁判球員都自己的方式可信嗎?
然後你前面講剛性,後來又講硬度
這兩個單位根本不同耶,要比硬的話擋風玻璃可是比鋼鐵還硬
噓 qwe172839: 笑死 除了1 其他都有公布數據或是結構圖 和粉真幽默 08/15 22:00
推 nctudaniel: 1.撞測用動畫模擬 鋁罐車08/16 00:16
→ nctudaniel: 2.雖然沒撞測影片 但有mpa分佈圖 應該還ok3.有撞測影08/16 00:16
→ nctudaniel: 片 但從影片來看 應該沒lancer硬 而且才撞正面跟側面408/16 00:16
→ nctudaniel: .有撞測影片 且公佈齊全 但有分數出來更好 從影片來08/16 00:17
→ nctudaniel: 看 感覺不錯5.沒撞測影片 mpa分佈圖應該也沒 可能是鋁08/16 00:17
→ nctudaniel: 罐08/16 00:17
我倒想問問,看到鋼材分布圖就能算出安全性了?
Livina門邊防撞樑用到1570 MPa的鋼材
https://i.imgur.com/tBcTZDG.jpg
Subaru SGP車體只有B柱用1470 MPa鋼材
https://i.imgur.com/MrvIcEg.jpg
所以Livina很安全囉?
一台車結構鈑件幾百個
https://i.imgur.com/CU9kivN.jpg
用上快10種不同強度的鋼材很正常,還有鈑件厚度、鈑件搭接、截面形狀、焊點等資訊
車廠給消費者看一張最粗淺的鋼材分布圖,根本不可能直接類推安全性
P.S.設計階段一定是透過模擬來評估整車安全性,不要以為那只是做做動畫好嗎.....
試量產車造出來才有可能做安全性試驗
→ justin332805: 國產Lancer撞測08/15 18:44
→ justin332805: 至於相不相信ARTC看你自己08/15 18:45
→ justin332805: 當初這影片在FB一堆人留言08/15 18:45
→ justin332805: 台灣車商送測車跟市售車車體結構不同08/15 18:45
→ justin332805: 不像國外是直接拉市售車回來撞08/15 18:45
公布影片也不算什麼啦
舉個明顯例子,Model3跟S60的立柱偏撞
https://www.youtube.com/watch?v=bs4DXNVojGk
影片看起來S60的A柱變形較大,所以Model3表現比較好?
那怎麼反而S60駕駛座的假人承受作用力(G值)較低?
https://i.imgur.com/IOwrBd9.jpg
這是因為Volvo有SIPS側撞防護系統
https://www.youtube.com/watch?v=k4Os8HAOGxQ
利用分散側撞衝擊的結構設計,加上撞擊時座椅向內傾,來達到對乘客的保護
而這可是Volvo在1991年就提出來的設計
所以用影片能看出安全性嗎? 也未必!
中國車廠多的是撞測完整車看起來很完整,假人卻承受過大G值的例子
安全性不是看鋼材分布、看撞測影片就能知道
也不是看品牌既定形象或主觀認為
沒有NCAP前國產車都只是過最最最基本的法規撞測,安全性根本沒得比較啦!
