推 reallocust:可是像側撞方面(side impact),除了速度,大小以外,我一 01/29 00:22
→ reallocust:直找不到那輛台車的重量數據.且重量關乎動量,個人覺得 01/29 00:26
→ reallocust:重量才是最重要的 01/29 00:27
推 Ecclestone:也是 不過如果材質確定 大小確定 重量就確定了 01/29 02:17
這裡 我整理出一些公式
複習高中物理....XD 離我好遠了
有錯請指正
碰撞前 m1 v1 m2 v2 碰撞後 m1 v1' m2 v2'
碰撞係數 e=(v2'-v1')/(v2-v1)
碰撞後速度
m1-em2 m1+em1
v1'=----------v1 + ---------v2
m1+m2 m1+m2
m2+em2 m1-em2
v2'=--------- v1 + -------- v2
m1+m2 m1+m2
假設 測試車質量m1 v1=0 撞擊用台車 m2 v2
則 撞擊後測試車
m1+em1
v1'=---------v2
m1+m2
測試車所受到的動量
P= m1v2(m1+em1)/ (m1+m2)
受到的動能
m1(m1+em2)^2 v2^2
KE=------------------
2 (m1+m2)^2
...........
剩下請強者繼續分析了
究竟車重和撞擊後受到的衝擊傷害 有沒有關係
不過也很難說 現在的造車設計 都有潰縮區
吸收撞擊後的能量 保護車內的乘客
在F1賽車上 最早出現這種概念的是
1981年 McLaren設計出的安全車艙概念
在駕駛艙周圍使用很硬的材料
在外面則用容易破碎的材料 吸收撞擊的能量
所以在車禍發生的時候 可以看到 破片滿天飛
而車手卻很安全
我覺得最可怕的是 2003年巴西站 Jaguar車隊的Mark Webber
撞到連引擎都分離了 駕駛艙還是完整

You think you have a limit and you'd better go for this limit and
you touch the limit. OK, this is the limit. As soon you touch this
limit, something happens to you: Suddenly you can go a little bit
further. With your mind power, your determination, Your instinct
and your experience as well.
You can fly very high ~Ayrton Senna da Silva
