Mechanical Low Frequency Vibration Test Equipment

Structural vibration testing and analysis contributes to progress in many industries, including aerospace, auto-making, manufacturing, wood and paper production, power generation, defense, consumer electronics, telecommunications and transportation. This application note provides an introduction to the basic concepts of structural vibration.

Low Frequency Vibration an overview ScienceDirect Topics

Low frequency vibration between about 2 and 80 Hz is perceived as feelable whole body vibration. This tends to be associated most with heavy freight trains at particular sites. Higher frequency ground-borne vibration from about 30 to 250 Hz causes the walls, floors and ceilings of rooms to vibrate and radiate low frequency noise.

Analysis of Vibration Characteristics of Centrifugal Pump

Mechanical seal is a kind of shaft sealing equipment. Face wear is one of the main causes of mechanical seal failure. Mechanical seal condition is also related to the reduction of energy consumption and carbon emission. Therefore, we need to detect the centrifugal pump seal condition. At present, vibration signal is a common method for fault monitoring and diagnosis of centrifugal pump.

Mechanical and vibration laboratory test equipment functions 1. The well-designed dynamic circular frame has higher axial resonance frequency. 2. Double magnetic circuit, low leakage flux, compact and reasonable structure. 3. Rocker roller bearing is straight and import oriented, composite rigidity oriented and eccentric bearing capacity.

Sep 21, 2020 Acceleration force is best measured when it is known that all the troublesome vibrations occur at high frequencies, that is, above 60,000 cpm. For example, in detecting high frequency turbine blade vibration in the presence of many low frequency vibrations, acceleration will assist in emphasizing the high frequencies.
