When the mass is pulled down from the start position and released the mass moves just like the vibration waveform shown in the graph on the right Frequency means the number of times that vibrating object generates a repetitive motion in 1 second
Get PriceThis means when using the same motor on the two objects, the vibration amplitude would feel much smaller in the heavy object even though the motor has the same force. Another aspect of the motor is the vibration frequency f fracMotor Speed RPM60 The displacement is directly affected by the vibration frequency.

Get PriceUnits used by those who feel that the vibrations power is more important than its amplitude based on Peak Units are used worldwide but are in more frequent use outside the Western Hemisphere Displacement is a distance usually measured in mils 1 mil 0001 or in microns
Get PriceThree simple terms are most frequently used in discussing vibration These are 1 Displacement Also known as amplitude is defined as the magnitude of the motion under study generally measured as peaktopeak or double amplitude in mils thousandths of an inch These measurements are most important in the study of deformation or bending of structures
Get Priceered the amplitude of the wave as the physical displace ment of the fork ends to either side of the rest position In addition to Displacement we can also describe the movement of the fork leg in terms of its velocity and its acceleration The form and period of the vibration remain the same whether it is the displacement velocity or ac

Get PriceNov 08 2017 In the derivation of the equations of motion of a harmonic oscillator we assume that the amplitude is small so even after doubling it we still remain well within this approximation In such case we can derive an expression for the oscillation
Get PriceDec 12 2016 Every vibration or oscillation has three characteristics Amplitude time period and frequency Amplitude of vibration The maximum distance to which the bob of a vibrating pendulum goes from its central position is called amplitude of vibration or amplitude of oscillation The distance AB is the amplitude of vibration of this simple pendulum
