    Abstract: 本文回顧兩種被廣泛採用於產生一維路面之方法,亦即成形濾波器與正弦函數近似法,這些路面可用於四分之一(或二分之一)車懸吊系統控制器模擬上。本文主要貢獻在於,吾人發現於成形濾波器法中,產生路面之一階系統之時間常數與路面等級是獨立無關的。為完整性,文中亦詳細推導正弦函數近似法中各個頻率之振幅。
    In this work we review two of the most commonly adopted methods, namely shaping filter and sinusoidal approximation, for generating one-dimensional random road profiles, that are used in the simulation of a quarter car (or half car) vehicle suspension control system. The major contribution of this work is the following: for the shaping filter method, it is found that the time constant of the first order transfer function generating the road profile is independent of the grade of road. While for the sinusoidal approximation method, a detail derivation of the amplitude of each sinusoidal function is re-derived for completeness.
