Two methods have been presented in this paper to treat this case. They are tangent method and minimum equivalent linear damping method. Their relation has been found, too.
为此，本文提出了两种处理方法，即切线法和最小当量线性阻尼法，并找出了它们的关系。
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。
The equivalent damping coefficient between linear and nonlinear viscous damper is investigated.
