inherent damping meaning in Chinese
固有阻尼
Examples
- Stay cables of the long - span cable - stayed bridges are susceptible to vibration under wind loading , or wind incorporated rain excitation , or deck motion due to high flexibility , relatively small mass and very low inherent damping , such as vortex shedding , wake galloping , parameter resonance and wind - rain induced vibration . large - amplitude vibration of cables may reduce the life of cables and threaten safe traffic , and has been considered today as one of the most critical problems for this type of bridge
大跨度斜拉桥拉索具有较小的质量和极低的阻尼，在风、风雨及桥面振动等外部激励下极易发生振动，如涡激共振、尾流驰振、参数共振和风雨振等，拉索的大幅振动对拉索的使用寿命和桥梁安全运营构成极大威胁，它已成为大跨度斜拉桥急需解决的关键问题之一。 - It is shown that vibration suppression efficiency of these kind of treatments depend much more on the viscoelastic layer thickness , material properties and the piezoelectric layer thickness . secondly , a linear quadratic regulator and output feedback are used to actively control vibration . it is shown that placing the active element on the opposite side of pcld or underneath pcld is capable of vibration suppression with lower control effort and more inherent damping
定义了主被动混合阻尼结构控制性能指标：被动抑振性能指标、主动抑振性能指标、控制能量指标和控制力性能指标；然后，基于状态反馈最优控制律，根据定义的控制性能指标分析粘弹性阻尼层厚度、粘弹性阻尼材料参数、压电作动层厚度对主被动混合阻尼结构振动控制性能的影响，得到了一些有价值的结论。
