Define vibration. vibration synonyms, vibration pronunciation, vibration translation, English dictionary definition of vibration. n. 1. a. The act of vibrating. b. The condition of being vibrated. 2. Physics a. A rapid linear motion of a particle or of a
[translate] a(Another approach to reduce vibration and noise in helicopters is based on dynamic changes to the spanwise blade twist using embedded anisotropic piezocomposite actuators such as Active Fiber Composite 正在翻译,请等待...[translate]...
aAnother drawback is that it tends to transmit noise and vibration from the road directly into the body shell, giving higher noise levels and a harsh feeling to the ride compared with DWs, requiring manufacturers to add extra noise reduction or cancellation and isolation mechanisms. 另一个缺点...
Conjugation with another double bond lowers the frequency and often increases the IR band intensity. Imino (CN) stretching vibrations result in strong Raman and moderately strong IR bands. Most CN stretching vibrations occur between 1690 and 1630 cm−1. Azo (NN) stretching vibrations give rise ...
Another set of experiments is carried out by attaching helical wires, to make the VIV suppression system, direction insensitive. Unlike strakes, helical wires can be mounted without causing a large projected area, which would be normal to the free-stream flow. Hallam et al. (1977) suggested ...
Furthermore, this study reveals that the prediction accuracy of hybrid models is less affected by multicollinearity because of the optimization algorithm. The external cross-validation and literature validation confirm the prediction capabilities of model PPV11. The ANOVA and Z tests reject the null ...
An organism vibration measuring device is for measuring a vibration of a portion of an organism which is put in an alternating magnetic field. The organism vibration measuring device includes a vibrat
Consequently, the effective utilization of tool, monitoring of tool wear, and estimation of useful life of tool are also another significant aspect that needs to be addressed. Also, to analyse the impact of active vibration control on the tool wear, RUL and surface finish necessitates the ...
mechanical noise. The structural attenuation essentially reflects a type of transfer function of the system, which is measured by the ratio of the output of the system (response) at a certain location to the input of the system (i.e., the driving force) at another location. Different ...
