.... The ceramic bearing successfully transmitted torque and speed through the duration of the experiment, and vibration did not increase over time. This experiment gives confidence that fully ceramic bearings may be utilized to improve power density and corrosion resistance. In addition, this experiment also...

... Abstract Shipboard vibration has been identified as having the potential to cause degradation of 3D printer performance. A proposed mitigation for this effect is to actively monitor vibration of the ship deck and critical parts on the printer. A series of tests are conducted wherein a MIL-STD...

... controllers. LRAs use a coil attached to the motor chassis to generate a magnetic field. This magnetic field causes displacement of a magnetic mass that is attached to the LRA chassis using a spring. The spring acts to return the mass to its equilibrium position, causing it to vibrate. The physical design...

... Abstract Fixed passive vibration absorbers (FPVAs) are widely used on power lines and other continuous systems, but they are inherently limited since changes in wind conditions affect absorber performance due to changing mode shapes. A mobile damping robot (MDR) can overcome these limitations...

... implications for the MDR’s development as current methods of vibration control do not adequately address fatigue failure caused by wind-induced vibrations (WIV). Fixed passive vibration absorbers (FPVAs) are widely used on power lines, but they are inherently limited by their fixed nature since changes in wind...

... Abstract In this paper, we study the trouble diagnosis of diesel valve train by sound intensity, especially by the technique of the Gated Spectrum Analysis. To check the efficiency and reliability of our sound intensity measurement, we record vibration signals and sound intensity simultaneously...

... Abstract In this paper, the application of the principal-component analysis method in fault diagnosis is explored. Characterized as fast and precise, this method can be directly used for analyzing gear noise and vibration signals in time domain. The principal component method and its 1 error...

... Abstract The fundamental issue confronting a vibration test engineer is how to obtain the best representation for the natural frequencies and corresponding mode shapes of a mechanical system. In the case of a structure such as a vehicle that has rigid body degrees of freedom, a vibration test...

.... In this paper, the vibration analysis of high speed, stepped thrust gas film bearings considering the inertia effects is described. In the numerical analysis, the static and dynamic pressure distributions in pocket and land regions are evaluated from the generalized Reynolds equation considering the centrifugal...

... Abstract This paper describes the influence of bearing alignment (vertical position) on vibration of multi-rotor-bearing system. The rotor-bearing system used in this study consists of three rotors and six bearings. It is designed to have the equivalent dynamic characteristics to the turbo...

...-induced swing of ropeway carriers has attracted many researchers. It had been said that it was impossible to reduce the vibration of pendulum type structures such as ropeway carriers by a dynamic absorber. But in 1993, Matsuhisa showed that the swing of carrier can be reduced by a dynamic absorber...

... Abstract Vibration generated by underground railways is difficult to control because of the very limited space available in a tunnel. A popular approach is to use ‘floating slab track’ whereby the rails are fixed to a large concrete foundation separated from the tunnel wall by a resilient...

... Abstract Placement and orientation of fasteners in assemblies is generally based on convenience or static load and strength considerations. Vibration and other dynamic loads can result in loosening of threaded product, particularly when cyclic shear stresses are present. This paper investigates...

... Abstract Several experiments and analyses have carried out in the field of brake squeal and there are many suggestions to be found in the literature as to the cause of brake squeal. In this paper a mathematical model for friction-induced vibration and noise generation is used to study...
