The screen of the linear vibrating screen is composed of two screens with small mesh sizes. For the sake of simplifying calculations, only a single layer screen is studied. The linear vibrating screen moves in a reciprocating linear motion with a sinusoidal trajectory, making the boundary of fluid flow highly complex.
The quasi-static method is commonly used to calculate the dynamic stress of vibrating screen beam structures. D'Alembert's principle is employed in this method, with the inertia force of the rigid body treated as a static load, the deformation and stress of the beam are calculated by equilibrium equations.
Vibration signal processing is the foundation of the machinery status monitor and fault diagnosis. Methods for stationary signals and non-stationary signals processing are summarized in this paper. Moreover, a new 3-DOF model of vibrating screen for its fault diagnosis, as well as its dynamic analysis, is presented to more entirely describe the …

"A vibrating motor imparts both linear and vertical motion to a deck or screen surface, causing particles to move across the screen. As these particles encounter the openings in the screen mesh, smaller particles pass through, while larger ones are retained." The applications of vibrating screens are diverse, spanning various industries.
