Most musical instruments work in the same way. For example, in a brass instrument, the vibration of the player's lips against the mouthpiece creates the initial vibration, and when this matches the resonant frequency (or a ple of it) for the size of the pipe he or she blows into, there is resonance, and the amplitude of oscillation increases notably and produces an audible tone.

Get PriceResonance is probably one of the five common causes of excessive machine vibration. Identifying a resonance frequency effectively can be challenging. We need to positively identify the natural frequency by performing at least two different tests such as impact test, coast down peak hold, coast down peak phase or impact test using a force hammer. Once the resonance is confirmed, either .

Get Pricevibration frequencies may be virtually impossible. Another possible solution to solve a resonance problem is to install a dynamic absorber, a device designed to have the same resonate frequency which, through its own vibratory force, will counteract the initial exciting force. This paper outlines the theory of dynamic absorbers, presents several case histories of resonate problems solved by ...

Get PriceA structure will have a resonant frequency in each of its 3 directional planes (x, y and z, or as we call them, horizontal, vertical and axial). 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 ...

Get PriceIn order to study the resonance characteristics of rock under harmonic excitation, two vibration models have been presented to estimate the natural frequency of rock encountered during the drilling. The first one is a developed single-DOF model which considers the properties and dimensions of the rock. The second one is a -DOF model based on the principle of least action.
