黏性阻尼

振动压路机橡胶减振器动刚度及黏性阻尼计算方法研究

Research on the calculation method for dynamic stiffness and viscous damping of rubber isolators on vibratory roller

减小阀组的阀芯质量和黏性阻尼系数可减小阀芯运动与活塞运动之间的相位差，提高系统容积效率；

Reduction of the spool moving mass and viscous damping coefficient minifies the phase offset between the spool and the piston movements and leads to the increase of system volumetric efficiency .

考虑土体三维波动效应时黏性阻尼土中桩的纵向振动特性及其应用研究

Theory on longitudinal vibration of pile in viscous damping soil layer considering three-dimensional wave effect and Its Applications

假定桩为竖直、弹性、等截面体，土为线性黏弹性体，其材料阻尼为黏性阻尼。

The pile is assumed to be vertical , elastic and of uniform cross-section , and the soil is considered as a linear viscoelastic layer with viscous damping .
