Improvement for design of beam structures in large ...

 · Demand for large vibrating screen is huge in the mineral processing industry. As bending and random vibration are not considered in a traditional design method for beam structures of a large vibrating screen, fatigue damage occurs frequently to affect the screening performance. This work aims to conduct a systematic mechanics analysis of the beam structures and improve the …

Influence of Load Weight on Dynamic Response of Vibrating ...

 · The dynamic response of the vibrating screen has a great impact on the screening efficiency and fatigue life of the structures. For the conventional dynamic design, the consideration of the influence of load weight on dynamic response is lacking. So, in this paper, taking a very common vibrating screen used in tunnel construction as an example, the relationship between the screen …

Vibrating Screen Types & Working Principle [How To Choose ...

linear vibrating screen is driven by double vibrating motors. When the two vibrating motors are rotating synchronously and reversely, the excitation force generated by the eccentric block offsets each other in the direction parallel to the axis of the motor, and overlaps into a resultant force in the direction perpendicular to the axis of the motor, so the motion track of the linear vibrating ...

Structural Damage from Adjacent Construction Projects ...

 · Extended exposure to vibration over a period of time can yield more potential for densification resulting in more settlement of the soil. Direct energy from vibration which can damage structures is a function of the type of construction equipment or method used (i.e blasting), the distance away from the source, along with type of soil present.

A tutorial on design analysis for random vibration

The von Mises stress is often used as the metric for evaluating design margins, particularly for structures made of ductile materials. While computing the von Mises stress distribution in a structural system due to a deterministic load condition may be straightforward, difficulties arise when considering random vibration environments. As a result, alternate methods are used in practice.
