This study used the 2D boundary element method in time domain to examine the screening effectiveness of open trenches on reducing vibration generated by a high-speed train. The parameters included configurations of the trench, train speed, the distance between the source and the trench, and the Poisson’s ratio of the soil. A reducing displacement level (in dB scale) was defined and used to ...

The principle of separation promoted by vibration screening is related to the movement imposed by the equipment on the material over the screen . The displacement and velocity of the material over the screen involves a complex mechanism, a function of the mechanical action and particle bed characteristics ( Harzanagh et al., 2018 , King, 2001 ).
2020-7-3 Screening for high overall vibration levels might seem like a logical first step. But overall vibration alarms will miss many emerging faults, because acceptable vibration levels from imbalance and flow turbulence on pumps and fans and background vibration often will mask low amplitude vibration from bearings and other critical components. By ...
Parallel vibration sieves have good screening effects.They have got wide attention in sieve studying.To implement the optimal control of a parallel vibration sieve,its screening characteristics should be studied in detail.Investigating the structure of a parallel vibration
Our vibration screens are characterized by high-frequency vibration, which is directly transmitted to the screen cloth. The screen housing remains static and does not move with the screen. This is not only energy-efficient and extremely precise , but also protects the building or steel structure from dynamic loads during screening, since no ...

KEYWORDS: Excitation, Vibratory, Analysis, Screening, Efficiency. 1.0 INTRODUCTION Vibration is any motion that repeats itself after an interval of time (Singiresu, 2004). Everything on earth vibrates, and the vibration of a system involves the transfer of kinetic energy to potential energy and vice versa.
2020-7-7 Vibrating screens are the most important screening machines primarily utilised in the mineral processing industry.

This paper provides a review of various investigations concerned with vibration isolation using trench barriers and factors affecting their performance, also extracts design recommendations, because there is no exact conclusion of researches in this field. Vibrations induced by different sources can be seriously harmful to structures and occupants.
2020-7-6 The screening process can range from providing a basic check of an electronic system prior to shipment (commonly called burn-in) to the application of much more severe environmental profiles, often involving many temperature and vibration cycles at extreme limits. The benefits of screening depend on the maturity of the manufacturing process ...
