推 Habanero:果然是這樣! XD 02/27 18:32
→ Habanero:那為什麼前叉反而比較貴呢?這是另一個疑惑XD 02/27 18:33
如果後避震整組構造跟前岔一樣的話...
不只我,大部分的消費者都很難吃得消Orz
推 neo718:仲生的後避震原廠才600、700? 我的原廠一隻就要一千了.= = 02/27 19:16
雙槍避震原廠一"隻"600、700沒錯呀
推 chunchien:想請問阻尼感消失了,但是卻不會觸底,可是會振到有點 02/27 19:39
→ chunchien:難過,這樣避震的狀態是?該換了?還是有別的方法呢? 02/27 19:39
觸底不是說彈簧壓到底的觸底
也包含了避震的「做動範圍」
可能彈簧沒被壓到底沒錯
以前岔來說就是裡面的內外管已經被壓完
後避震也是一樣
當然老舊的避震阻尼衰退,造成避震上下直直搖也是會震到難過的地步
→ domago:有人被水桶了XD 02/27 21:36
Orrrrrrrz
推 OhHIyoPaNg:我還是有點看不懂耶...囧 02/27 21:37
→ OhHIyoPaNg:拿一台車舉例一下或許我會比較能領悟XD 02/27 21:38
我打中文吶~~
哪邊看不懂也說一下+_+
在打那篇文章的時候已經很努力講白話一點了Orz
不然我在講一次重點好了
彈簧本身會來回振盪
阻尼就是要消除他的振盪XD
下面是兩個有關阻尼的動畫
雖然是大陸的網頁不過應該是沒有毒XD

推 greg60711:感覺好像在算ODE XD 02/27 20:20
振盪力學、電路學RLC(電阻電稈電容)電路就都是在算ODE XD
應該說...他們的物理特性剛好會形成二階或是高階的微分方程
(真他X的巧合啊...)
如果微方的特徵方程式所算出來的特徵解
判決式剛好是小於零(b^2 - 4ac<0 )
那就是underdamped,這時候他的通解會是cos和sin的組合解,且遞減
所以造成了阻尼的效果XD
如果判決式=0,那就是這個阻尼沒有效果
振盪一樣的再繼續
如果是>0,那這個根本不叫阻尼,而是叫加強器了XDD
