resonance vibration

resonance vibration

[′rez·ən·əns vī‚brā·shən]
(mechanics)
Forced vibration in which the frequency of the disturbing force is very close to the natural frequency of the system, so that the amplitude of vibration is very large.

Resonance vibration of vehicle is very common and severe, so it is necessary to look at the effect of this kind of vibration induced by SRM vertical force.
In the flexural vibration tests, the specimen was suspended by threads at the nodal positions of the free-free resonance vibration mode [f.sub.n] and excited along the depth direction with a hammer (Fig.
The limits in the use of this mechatronic workpiece fixture derive from the weight limitation of the workpiece and come along with the frequencies, which have to be selected to obtain a resonance vibration.
For the free vibration of the whole system, appearing vertically and horizontally along the frame, the lowest natural frequencies lied out of the range of excitation frequencies, thus the resonance vibration could not occur.
The design of the Maestro end mills reduces resonance vibration and results in smooth, silent machining operations without chatter.
Section 4 illustrates the torsional resonance vibration characteristics via a numerically simulated signal analysis.
The static bending modulus of elasticity (MOE) of small clear wood specimens was about 15 and 20 percent greater than the dynamic MOE of green logs based on resonance vibration ([E.sub.fr]) and stress wave ([E.sub.sw]).
Chatter-free machining results from a patent pending flute design and constant unequal flute facing to avoid resonance vibration. VariMill TiA1N-coated end mills are available in 1/4" to 3/4" diameters in stub lengths; 1/4" to 1 1/4" diameter in regular lengths.
The closer to resonance vibration, the greater the deflection of the deckboard.
Damping can be used to control the excessive resonance vibrations which may cause high stresses leading to the permanent failure.
