1) damped harmonic oscillation
阻尼谐振动
2) damped non-harmonic vibration
阻尼非简谐振动
3) simple harmonic oscillation with damping
阻尼简谐振动
1.
The impacted bridge was considered to do simple harmonic oscillation with damping after impact.
认为桥梁在受到撞击后做阻尼简谐振动,提出了如等效振幅、等效弹性系数等概念。
4) underdamped harmonic motion
弱阻尼谐振运动
6) resonant damping
谐振阻尼
1.
The freely decaying oscillation signal,in which both the resonant frequency and the resonant damping information are carried,is sampled and processed to obtain both the resonant frequency and resonant damping coefficient of the resonator at the same time.
通过对含有谐振频率和阻尼信息的自由衰减振动信号的采集及处理,同时得到了谐振器的谐振频率及谐振阻尼参数。
补充资料:简谐振动(harmonicvibration)
【简谐振动】(harmonicvibration)振动的一种形式。一个作直线振动的质点,如果取其平衡位置为原点,取其运动轨道沿`x`轴,那么当质点离开平衡位置的位移`x`随时间`t`变化的规律,遵从余弦函数或正弦函数时:`x=Acos((2\pi)/Tt \phi)`,这一直线振动便是简谐振动。式中`A`表示质点离开平衡位置时`(x=0)`的最大位移绝对值,称“振辐”,`T`是简谐振动的周期,`((2\pi)/Tt \phi)`角称为简谐振动
