24-10-2020· Resonance is the result of an external force vibrating at the same frequency as the natural frequency of a system. Natural frequency is a characteristic of every machine, structure and even animals. Often, resonance can be confused with the natural frequency or critical frequency.

Resonance serves to amplify the vibration due to whatever vibration force is present at (or near) that resonant frequency. It is important to note that resonance does not cause vibration it amplifies it. Resonance problems occur in two primary forms. They are: Critical speeds occurs when a component rotates at its own natural frequency.

The resonant frequency is f o. Effect of damping on resonance graph.

The vibration being amplified could originate from a number of sources: unbalance, misalignment, pump vane vibration almost any source of vibration can cause resonance. And that vibration does not have to be a problem in itself. For example, resonance can cause slight unbalance to appear as if the rotor is seriously out of balance.

01-10-2017· From the knowledge of vibration machines, it can be easily affirmed that the frequency of vibration of any vibrating equipment must not equal the natural frequency of the systems. According to Nianquin [14],when the resonance occurs, theoretically the amplitude is infinite; therefore it could lead to the damage of the screen structure or even cause high noise levels.

Screen Equipment Fluid Systems Inc . During Circular vibrating screen especially heavy type start-up and shutdown because of through the resonance area the amplitude of the sieve machine will increase sharply and causing the spring serious overload shorten service life belt is easy to be damaged severe vibration may also damage

Objects which are free to vibrate will have one or more natural frequency at which they vibrate, If an object is being forced to vibrate at its natural frequency, resonance will occur and you will observe large amplitude vibrations. The resonant frequency is f o. Effect of damping on resonance graph.

A system is said to undergo free vibration when it is initially disturbed from its state of rest by some means and the system starts to execute to and fro motion. So here at all times t>0 there is no external force acting on the system except at t...

07-06-2016· Free vibration occurs when an object is given an initial displacement and then allowed to “ring down” with no external force acting to keep it in motion. The frequency that this free vibration naturally wants to occurs at is known as the natural frequency. If an object is being forced to vibrate at its natural frequency, resonance will occur.

The vibration being amplified could originate from a number of sources: unbalance, misalignment, pump vane vibration almost any source of vibration can cause resonance. And that vibration does not have to be a problem in itself. For example, resonance can cause slight unbalance to appear as if the rotor is seriously out of balance.

In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration.
