finite element analysis of dual-frequency vibrating screen

Abstract: In order to study the stress distribution of dual-frequency vibrating screen and ensure the screen box has sufficient strength and longevity, a finite element model of dual-frequency vibrating screen was built, and the stress, modes and fatigue life of the screen box were analyzed. The results indicate that, the stress concentration appears at the contacting parts between the crossbeam and the stiffener of motor seat, the crossbeam, L-type stiffening plate, baffle …

fatigue failure analysis of vibrating screen spring by

Vibrating screens are often used in the mining industry to separate mineral particles by size. In many designs, spring arrays are used to provide the system with the necessary stiffness for screens to vibrate in a controlled manner. Naturally, these springs are subjected to varying loading cycles, which can cause their premature fatigue failure. This behavior has been studied by means of finite element analysis …

Abstract: The large-scale and modular design of vibrating screen brings about the trend that the screen separate from screen frame. The separation of the screen frame and the screen changes their dynamic characteristics. By making modal analysis and harmonic response analysis in ANSYS, the dynamic data of the screen and the screen frame was obtained, such as the natural frequencies, mode shapes, …

paper: vibrating screen modelling with the numerical

In this paper, the NMM is applied to the simulation of vibrating screen. The vibrating screen is widely used in mining, construction material, transportation, energy and chemical industry for size separation. The efficiency of the screen is determined by the size and the shape of the screen openings, the amplitude and the frequency of the screen motion
