How vibration analysis can detect alignment .

24.02.2014 · "Generally with the former, vibration data are collected by plant personnel or a remote representative and conveyed to an Internet-based database for analysis and reporting. This approach is quite cost-effective, in that many machines can be assessed on a frequent basis without the vibration analyst being on site. In this scenario, vibration spectral data are directly compared with an ...

A Vibration-Related Design Parameter .

High-speed elevator horizontal vibration (HsEHV) is a problem that seriously affects ride comfort. To solve this problem, a design parameter optimization method for HsEHV reduction was studied. A dynamic equation of HsEHV was established, and its response value was calculated using a precise integration method. The influence of the design parameters on horizontal vibration was also analyzed.

Vibration-induced boundary-layer destabilization .

When horizontal vibration is applied to the convection cell, a strong shear is induced to the body of fluid near the conducting plates, which destabilizes thermal boundary layers, vigorously triggers the eruptions of thermal plumes, and leads to a heat-transport enhancement by up to 600%. We further reveal that such a vibration-induced shear can very efficiently disrupt the boundary layers ...

Shaft alignment - Wikipedia

Shaft alignment is the process of aligning two or more shafts with each other to within a tolerated margin. It is an absolute requirement for machinery before the machinery is put in service. When a driver like an electric motor or a turbine is coupled to a pump, generator, or any other piece of equipment, it is essential that the shafts of the two pieces are aligned.
