### Understanding of resonance essential for solving vibration

When the operating speed reaches the resonant frequency of the rotating element, the rotating element distorts and the vibratory forces increase significantly. It is important to properly distinguish between structural resonance and rotor critical speed. The term "critical speed" (without the word "rotor") is somewhat ambiguous.

30.03.2020· Ideal frequency vibrations For years, the frequency of our planet has been 7.6 Hz. According to the physicists, it is called the Schumann resonance. It is according, to the beat generated by lightning in the cavity between the earth and the ionosphere.

### Critical speed Wikipedia

As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration. The resulting resonance occurs regardless of orientation. When the rotational speed is equal to the numerical value of the natural vibration, then that speed is referred to as critical speed.

### Failures due to Natural Frequency Resonance. Bright

In a typical subcritical 600 MW 50 HZ steam turbine generator, with a normal opearting speed of 3000 rpm, critical speeds occur at 740 rpm and 2044 rpm. The different horizontal and vertical stiffness of the bearing and supports causes these two critical speeds.

### Motor and Drive System Resonance Problems and

Mechanical resonance occurs when an external source amplifies the vibration level of a mass or structure at its natural frequency. For a rotating mass like a motor or a pump, this occurs at the critical speed(s). Electrical resonance amplifies the magnitude of voltage or current, or both.
