strain modal analysis and fatigue residual ... - jvejournals

The displacement and strain modal analysis of vibrating screen beam is carried out, the results show that the relative deviation of the modal frequencies between intact and damaged beam is small, the displacement mode shapes of the damaged beam have no obvious variation, but the strain mode shapes have mutation peaks at the damaged location for the damaged beam. Therefore, a damage index is

structure optimization ofvibratingfeeder based on

Similar to vibrating feeders, vibrating screens are subject to a large dynamic load during the vibration process. To improve the reliability of large vibrating screens, Zhao et al. presented a new design of a hyperstatic net-beam structure and analyzed dynamic characteristics of it, based on the FEM, and the new screen proves to have much

vibrating screen

Abstract: A new control system of vibrating screen invert power source was designed according to the question of step regulation of current and power in vibrating screen in the use of MCU. Zero-voltage switching inverter is used to reduce the loss of switching devices in the main circuit and MSP430 MCU is the core of the control circuit

stepwise shape optimization of the surface of avibrating

The structure of a real vibrating screen is particularly complicated and mainly comprises a screen box, screen mesh, and vibration exciters. A simplified three-dimensional model of the vibrating screen, shown in Fig. 1, is established to reduce the complexity but realize the actual screening effect.Additionally, the sieving process in the simulation experiment is shown in Fig. 2

analysis of the dynamic forces acting on avibrating

The designed equipment presented in this work is a vibrating dewatering screen, model PVD 1206 1 A (), with a nominal length of 1200 mm and nominal width of 600 mm, which was developed with the upper double mechanism, driven by two motors via cardans .Its two mechanisms at the top, with unbalanced masses, cause a rectilinear vibration , , which transports the material through the sieve surface

a theoretical rigid body model ofvibrating screenfor

Springs are critical components in mining vibrating screen elastic supports. However, long-term alternating loads are likely to lead to spring failures, likely resulting in structural damages to the vibrating screen and resulting in a lower separation efficiency. Proper dynamic models provide a basis for spring failure diagnosis. In this paper, a six-degree-of-freedom theoretical rigid body
