Experimental Investigation on Vibration Control of Rotor-bearing System with Active Magnetic Exciter
vibration control rotor-bearing system active magnetic exciter
2011/7/28
Vibration control is an efficient way to minimize a rotating machine’s vibration level so that its vibration fault-free can be realized. While，several factors, such as unbalance, misalignment and inst...
Vibration Characteristics and Power Transmission of Coupled Rectangular Plates with Elastic Coupling Edge and Boundary Restraints
vibration power transmission coupledplate
2011/5/12
Coupledplate structures are widely used in the practical engineering such as aeronautical, civil and naval engineering etc.Limited works can be found on the vibration of the coupledplate structure due...
New Method to Measure the Fill Level of the Ball Mill: Part II—Analysis of the Vibration Signals
ball mill fill level vibration signal signal processing
2011/1/17
The exact measurement of the fill level is the key and basic problem for automatic control and optimized operation of the coal pulverizing system. Because the ball mill pulverizing system is non-linea...
Application of artificial neural network and wavelet transform for vibration analysis of combined faults of unbalances and shaft bow
Rotor test rig Rotor faults vibration analysis, unbalance
2010/12/30
The vibration analysis of rotating machinery can give an indication of the condition of potential faults such as unbalance, bent shaft, shaft crack, bearing clearance, rotor rub, misalignment, loosene...
Finite element study of correlation between intracranial pressure and external vibration responses of human head
intracranial pressure (ICP) finite element model
2010/12/30
In this paper, the correlation between intracranial pressure (ICP) and external vibration responses of the head was studied using finite element modeling. A two-dimensional finite element model of the...
Separate Control of High Frequency Electro-hydraulic Vibration Exciter
control valves electro-hydraulic system vibration exciter
2010/9/6
The working frequency of the conventional electro-hydraulic vibration exciters, which consist of a servo valve and a hydraulic cylinder, is generally restricted within a narrow range due to limited fr...
Nonlinear vibration signature analysis of high speed rotor due to defects of rolling element
Nonlinear dynamics rolling bearing ball passage frequency
2008/12/30
This paper presents a mathematical model to investigate the nonlinear dynamic behavior of a high speed rotor-bearing system due to defects of rolling elements. Two defects have been considered for the...
