實際上一台車有幾百件以上的的鈑件結構
https://i.imgur.com/TsP4DeG.jpg


只看車側部分
https://i.imgur.com/MfkNaNX.jpg

A/B/C柱除了內外鈑件(通常採用低強度),還會有N個補強件搭接而成

車廠給一般消費者看的鋼材分布圖
https://i.imgur.com/Doc0Hku.jpg


說到底就只是個"文宣"罷了,目的就只是為了"宣傳"
所以A/B/C柱簡化成用同色塊表示
真的有照實把每件都標出來?
另外就以CR-V標榜的590 MPa以上的鋼材接近全車一半好了
一半是指鈑件"數量"的比例,還是指"重量"比例?
單純只包含結構件?
還是連引擎蓋、葉子板、車內外、車頂這些蒙皮部分都算進去?
好吧~就算今天車廠吃飽太閒
在文宣上把所有鈑件結構的鋼材用料都標出來
難道這樣就有辦法直接判斷安全性了?
鈑件的厚度資訊、應變率
焊道、焊點、鉚接、螺栓、打膠的位置分布
焊點層數(雙層/三層),焊點或膠合的機械特性(抗拉、剪切強度)
https://i.imgur.com/roEVCIn.jpg

這些都是執行碰撞模擬的必要資訊
即便這些資訊都充足的前提下
一個有經驗的碰撞模擬CAE團隊也得花費數月
建Trimmed Body、BIW網格前處理、打焊(RBE2)設定、黏膠(C-bush)設定
甚至連座椅、模擬碰撞專用的假人模型都得加進分析模型
執行有限元模擬,計算碰撞下對乘客的傷害如何
https://www.youtube.com/watch?v=mPsUoD4mtQc
這些資訊量龐大到一般人
1. 根本不會想看
2. 看了也看不懂
所以勒
光憑車廠文宣提供那極為粗淺的鋼材分布圖
消費者哪有可能直接類推安全性
假設完全不考慮製造加工(沖壓),把整車鋼材強度都提高一定是好事?
引擎室的縱樑打孔設計
是為了撞擊發生時,透過鈑件彎折/皺褶變形(潰縮)吸收撞擊能量
確定該位置改成更高強度的鋼材對緩衝吸能一定有幫助?
想了解車用馬達特性
看T-N曲線、最大扭力、額定/峰值功率,甚至效率圖就綽綽有餘
難道需要公布槽極數、磁石位置形狀、稀土用量、銅線佔槽率這些細部資訊
同樣道理
想知道車體結構被動安全如何
等NCAP評鑑星等不好嗎? CR-V這種大眾車款N-CAP不可能不會測
再更細一點,看偏撞/側撞/立柱側撞下受測假人的傷害
或是要求基本必須滿足的法規撞擊測試加嚴跟上歐盟腳步
為啥非得鑽牛角尖
執著於看了也不能直接推論安全性的鋼材分布圖?

希望下一代的能儘快送測,給大家心裡有一個底,再
者tncap因為剛起步用較舊的規範,但是有承諾2-3年
後會到encap2022版,最終目標是同步,這是值得鼓勵
的,畢竟要時間改進,最後一般人提ncap直覺認為是e
uro ncap而非tncap吧
