By observation and analysis of the test data, changing the plate steel endshield of motor into the disc iron one can improve the rigidness of endshield, and reduce the axial vibration of motor.
Introducing a kind of dynamic capability study method which tested jumpiness of the sawblade made in Germany on the precision sizing saw machine, as well as vibration of principal rotation axle.
DNA - the ancient cabalistic Tree Of Life portrayed in the Biblical Torah, is now coming to be viewed as a live vibrating structure, rather than a fixed tape recording.
In addition to rammers and smaller vibration plates ,a whole range of other products for the domestic market and for export worldwide is currently produced in the USA .
Based on the correlation principle, an algorithm to decomposite the damped free vibration signals of a two degrees of freedom system with close natural frequencies is put forward.
This paper introduces the principles of the vibroplatform,provides some methods for the detection and diagnosis of the servo valve,and makes the field monitoring of the synchronism of vibroplatform.
The issue of vocal cords vibrating in voice training is easy to lead to making voice dark,dry and coarse,raucity even caused pathological changes such as vocal cords polyp.
Elastic coupling is commonly used in roating machinery for connecting two shafts and delivering the power, for example, the spline coupling between engine and reducer or hydrodynamometer.
The cantilever taps across the surface with metronomic precision.But as it moves, it also behaves much like a tuning fork, producing overtones related to the fundamental vibration.
Except the centralized load impressed from plane other components and airload, the plane gun bay structure is also endured the wallop of the navigate gun launching.
It is composed of the XD-I vibroscope based on the string vibration and the XQ-I fibre tensile tester with pneumatic clamp operating and data processing function.
BACKGROUND: Various investigative tools, including direct visualization with stroboscopy and indirect observation with glottography, have been widely used for the observation of vocal fold vibration.
Applying the theory of rheodynamics and hydraulic theory, a relationship of damping vs. vibration velocity, electric field strength and gas-filled pressure has been set up.
The floor's supported by ten massive pads. These are constructed from rubber, and so are able to absorb any vibrations from outside and prevent them from affecting the auditorium.
Being out on the ice when it sings the most is a very special experience. If the ice cracks close to you, you can feel like a wall of vibration from the sounds almost knocking you down.
In this top graph of the red wiggly line, we're looking at the ground velocity in essentially metres per second. So, that's the velocity that the ground is vibrating up and down.
While the vibrating system on a typical phone requires 10 or more oscillations to reach full power, the Taptic Engine in iPhone 6s reaches peak output in just one cycle, and stops just as quickly.
