Amplitude: Represents the magnitude of vibration, the "severity" of damage to equipment or mechanical components. The units of amplitude are: displacement value (mm), velocity value (mm/sec), acceleration value (g) Frequency: Represents the source of vibration and the "cause" of damage to equipment or mechanical components.

Abstract. Dynamic characteristic and reliability of the vibrating screen are important indicators of large vibrating screen. Considering the influence of coupling motion of each degree of freedom, the dynamic model with six degrees of freedom (6 DOFs) of the vibrating screen is established based on the Lagrange method, and modal parameters (natural frequencies and modes of vibration) of the ...

Vibrating electric motor work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. As the strength of a current increases so does the strength of the magnetic field.

Longhole stoping is a productive exploitation technique for underground metalliferous deposits. The method consists of deep-hole blasting with increased explosive charges to excavate larger volume of ore from a single blast. However, large scale blasting produces hazards in terms of blast-induced vibration. The underground structures viz. drivages, cross-cuts, shaft pillar, shaft, decline, etc ...

DYNAMIC MOTION VIBRATION PARAMETERS Amplitude Amplitude of vibration on most machinery is expressed in peak-to-peak mils displacement. Amplitude, whether expressed in displacement, velocity, or acceleration, is generally an indicator of severity. It attempts to answer the question, "Is this machine running smoothly or roughly?".

The mechanical system vibrates at one or more of its natural frequencies and damps down to motionlessness. Forced vibration is when a time-varying disturbance (load, displacement, velocity, or acceleration) is applied to a mechanical system. The disturbance can be a periodic and steady-state input, a transient input, or a random input.

Vibrating tube densimeters are well-established tools for measuring fluid densities precisely at elevated temperatures and pressures. However, the conventional method of calibrating them utilises a model in which the apparatus parameters are represented as polynomials of temperature and pressure that contain a variable number of terms.
