If the excitation of the shockabsorber is greater, the control piston moves to its limit position so that oil ceases flowing through the bypass duct, meaning that the full damping force is available.
To avoid these two kinds of noise, the paper gived some requirements to the internal structure design of shockabsorber, such as piston valve system, bottom valve system, piston rod etc.
为降低或消除这两种减振器噪声，提出了对减振器内部结构如活塞阀系统、底阀系统以及活塞杆等的设计要求。

Based on the simulation model a simulation piston gap, at the end of the valve, the piston rod and sealing ring gap of oil leakage caused by the shockabsorber failure.
