Research on the New Drive of a Laboratory Screen with

2 天前 The super-resonance screen is placed into vibrating motion by the drive system, which most often consists of an electric motor, flexible couplings and an inertial vibrator. In such solutions, the amplitude of vibrations depends on the centrifugal force from all unbalanced masses mounted on the vibrator shafts, whereas the frequency of vibrations is dependent on

Factors Affecting Vibration of Linear Vibrating Screen

If an excitation frequency is close to the resonant frequency, resonance occurs. Furthermore, since the eccentricity has a centrifugal inertial force, bending vibration occurs, and if the rotational speed approaches a critical value, bending resonance occurs. 2.Bearing accuracy The linear vibrating screen has a large excitation force, which causes the bearing to withstand a large

What is resonance in vibration? Quora

Answer (1 of 5): Every body having mass and elasticity is capable of motion and when this motion repeats itself over a period of time it is termed as vibration. When any body is disturbed from its equilibrium position it vibrates. Take for example the spring mass
