Th international congress on sound and vibration, july , krakow, poland figure sound pressure levels near projection screen, rotational speed gantry Hz msec db reduction however, placing the triplex plate with foam on the top gantry, as shown in figure c, reduced the vibrations of the projection screen with an additional db, giving a total reduction of
Acoustically induced vibration development and use of acoustically induced vibration development and use of the energy institute screening method the vibrating screen is by far the most commonly used type of screening equipment this wide details
This is an example of frictioninduced vibration
At high mass flow rates and pressure drops, flow across a restriction eG a control valve, pressure safety valve or orifice plate will result in extremely high levels of broadband noise the consequential acoustically induced vibration aiv in the downstream piping can cause fatigue failures through the pipe wall at branch connections andor welded supports
Piping vibrations vibration of process plant piping can be a significant risk to asset integrity and safety this is often due to flow induced vibration fiv and acoustic induced vibration aiv, and is related to the flow of the main process fluid through the piping system other possible sources of piping vibration include mechanical vibration and pulsations from compressors and pumps
