Vibration Test Acceleration - Vibration Research

18.06.2020 · The resonance quality factor is 0.5 divided by the critical damping ratio (ζ). In FDS analysis, the quality factor is related to the Q of the filters used to generate the single/narrow band time waveforms. This value should be set greater than or equal to the sharpest resonance of the product within the test frequency range. Slope of the S-N Curve (m) The S-N curve displays an inverse ...

Mechanical resonance - Wikipedia

Mechanical resonance is the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system's natural frequency of vibration (its resonance frequency or resonant frequency) than it does at other frequencies.It may cause violent swaying motions and even catastrophic failure in improperly constructed structures including bridges ...

Understanding of resonance essential for solving .

Resonant vibration in mechanical structures such as pumps, turbines and motors occurs when a natural frequency is at or close to a forcing frequency such as rotor speed. When present, this condition can cause severe vibration levels by amplifying small vibratory forces from machine operation. Such problems often develop after a speed change has been implemented, as with retrofitting a machine ...

Solutions to Reduce Stepper Motor Resonance

When the operation speed matches resonance speed vibration will occur, as a result motor performance will be affected. The easiest way to avoid resonance could be simply changing operation speed, so the motor will not hit its resonance point. 2. Micro stepping at finer step sizes reduces oscillation. The coil in stepper motor will be energized in discretely, so rotor of the motor will tend to ...

Q factor - Wikipedia

In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as the ratio of the peak energy stored in the resonator in a cycle of oscillation to the energy lost per radian of the cycle. Q factor is alternatively defined as the ratio of a resonator's centre frequency to its bandwidth when ...
