“…Natural characteristics include natural frequency, natural vibration modes, and other modal parameters. The purpose of natural characteristic analysis is to avoid resonance and harmful vibration modes and improve the reliability and service life of the screen and screen frame (Ding et al, 2012).…”

“…Dynamic simulation has also been accepted as a useful diagnostic tool for potential damages to different parts of vibrating screens. For example, Ding et al (2012) performed modal analysis and harmonic response analysis to obtain the dynamic data of a vibrating screen, such as the natural frequencies, mode shapes, stress distribution, and strain distribution. They showed that the stiffness of the screen frame is higher than that of the screen, and the side plats and beams of the screen are the weak parts.…”

Even though vibrating screens have been used in mining industries for over a century, their use has often been cited as challenging in terms of understanding its dynamic responses to different operating factors, particularly those that affect the structural aspects. Among the various aspects of screen design, the control of vibrational energies imposed on various parts of the screen is of particular importance because these vibrations directly affect the separation efficiency and useful life of the screen. This study proposes the use of vibration absorbers to control the adverse effects of severe screen vibrations. The dynamic behavior of a medium-sized vibrating screen utilized in the aggregate industry was investigated using the finite element method for both spring/dashpots and conventional solely spring systems. The modeling process was performed in loaded and unloaded conditions and in three frequencies of 15, 23, and 27 rad/s. Numerical simulation results showed that the use of dashpots can significantly reduce the maximum stress in the screen, such that the maximum stress in the center of gravity of the screen at the optimal frequency of 23 decreased from 237 to about 97 MPa. Also, sieve modal analysis showed that the stress in the sieve equipped with the spring/dashpots system had a more uniform distribution. The results revealed that the use of vibration absorbers can be a promising solution to prevent damage caused by high vibrational energies in screens.

“…The discipline between the average temperature of pipe wall and the average heat flux through the wall was numerically analyzed for Super304H steel, and the variations of the oxide film thickness with heat transfer and flow characteristics were also examined. ANSYS software [1] can deal with thermal analysis of system or components. It can handle the heat analysis includes steady-state thermal analysis, transient thermal analysis and instantaneous coupling analysis.…”

In this paper, for Super304H steel, the growth law of oxide films and the heat transfer characteristics between the pipe and the working fluid were investigated by using numerical software ANSYS, which simulated comprehensively the effects of pipe size, flow rates of steam, flue gas temperature, and steam temperature on the formation and thickness of the oxide film. A bigger pipe wall thickness, a smaller steam flow rate or a higher flue gas temperature will lead the faster growth of the oxide film thickness, the heat flux density through the wall being smaller and the wall temperature being higher. With increases in steam temperature and thickness of the oxide film, the heat flux through the wall decreases with a small amplitude, and the average temperature of tube walls increases slightly.
