極有可能跟原廠避震器阻尼特性有關
先從避震器的試驗設備(absorber test system)講起
試驗設備長這個樣子

目的是取得避震器行程方向在不同速度下的阻尼力
每個顏色的圈代表在特定速度下,避震器阻尼力的變化(包含壓縮和回彈)

避震器阻尼特性曲線 (damping force curve)

縱軸是阻尼力,橫軸是避震器行程速度
可以發現設計上:回彈力>壓縮力
理想的避震器

low speed region會有較陡的曲線,high speed region曲線斜率下降
Having a compression curve like this allows for a stiffer low speed region
and better control of the unsprung mass
With the high speed compression falling off, the rough roads, curbs and bumps
will be absorbed by the suspension rather than transmitted to the chassis.
A linear low speed range will keep consistent feel during the handling
maneuvers.
回到原題,原PO覺得低速左右搖晃大
極有可能是Altis原廠避震器行程低速下提供的壓縮阻尼力不足
造成roll rate過大
※ 引述《chyi1004 (阿呆)》之銘言:
: 車買半年
: 和舊車tierra比起來
: 有大幅升級感
: 唯一不能忍受的是
: 低速20以下時左右晃動非常明顯
: 尤其是在停車場時
: 有時都會晃到有點暈
: 反而高速時比較穩定
: 會是什麼原因呢
: 因爲原廠避震走舒適路線
: 比較軟造成的嗎?
