The equivalent viscous damping ratio and the equivalent natural frequency are obtained by comparing the system with a purely linear, spring-mass-damper system of single freedom.
通过和单自由度线性弹簧-质量-阻尼系统进行比较，得到该带裂缝梁结构的等效自然频率和等效粘滞阻尼比。

By means of the feedback linearization procedure of differential geometry, an equivalent, fully controllable and linear model was derived via a homomorphic transformation for the AMT clutch system.
进一步应用基于微分几何的反馈线性化方法，将原非线性系统等价为完全可控型线性化模型。
