(2000-2021), on the vibration analysis methods used for frame rigid connection. II. BEAM THEORIES Frames are structures that are typically made up of multiple beam and column structures joined together with varying connection methods (bolted, welded, special connections, etc.). When dealing with these structures (portal, X-braced, L-
whole structure and {F(t)} is the external force vector. Under free vibration, the natural frequencies and the mode shapes of a multiple degree of freedom system are the solutions of the eigenvalue problem. [[K]−7 %8(] {Φ} = 0 where 7 is the angular natural frequency and Φ is the mode shape of the structure
Location. Crushers are usually located at a height of say - 15m above ground to facilitate easy feeding of coal from the overhead conveyors. The supporting structure is generally of an elevated steel or reinforced concrete framed construction. It is preferable to isolate such …

In industries, crushers [] and machines which use tools to break or compress materials into small fractional chunks or denser masses are known as crushers.At the same time, mines and foundries are very small enterprises except for the few mines. Over the past few decades, foundries developed iron casting technologies and began to supplant other metals in …
1. Introduction. It is critical to isolate the low-frequency vibration to maintain equipment safety, accuracy, and stability in various engineering fields [1].While rubber …
Based on research conducted by Nan, Z., Kai, M. et al. [26] on seismic isolated of contiguous structures using energy dissipation isolated layers, it is advisable to install the isolated layer on lower floors for optimal seismic isolated effects. To connect contiguous structures, a steel truss structure and elastic seismic isolated device can be utilized to …

The efficiency of vibration isolation of more than 95% will not cause any disturbance to the surrounding area. Furthermore, the low total weight of the spring supported fan protects from settlement of the sub-structure. MILLS / CRUSHERS Mills and crushers of all types, especially those in power plants and the cement industry, generate heavy

Damping in fixed base structure is considered to be 5%, whereas in base isolated structure the damping considered is 10%. Damping in base isolated model was greater, yet the storey displacement was found to be maximum. Storey displacement of base isolated buildings can be further reduced by increasing the damping of the structure.

The X-structure has been used for vibration isolation due to its nonlinear characteristic. Here, the use of an inerter-based X-structure vibration isolator is proposed to improve the dynamic performance of the traditional X-structure vibration isolator by exploiting the mass amplification characteristic of the inerter while satisfying the lightweight design …
the analyses, the natural-vibration frequency of a crusher on vibration insulators was assumed equal to 7 Hz in the horizontal direction. To avoid the development of other forms of …
Purpose Staggered story-isolated structures are widely used in various engineering applications. For such structures, earthquakes have different isolated performances under ordinary earthquakes and long-period earthquakes. Therefore, analyzing the staggered story isolated structures is necessary. A finite element model of a staggered story isolated …
The selection of appropriate blasting vibration limits for civil construction projects and quarry operations has a major influence on a project?s overall cost, duration, and environmental impact. In some cases, the application of an overly conservative limit may affect a project?s financial viability to a point where it may not even commence, despite passing all the …

The use of base isolation to protect a structure and its contents from earthquake damage has proven to be an effective anti-seismic strategy during past earthquakes. Modelling of the isolation system is one of the key steps in understanding the response of the structure and more importantly to evaluate the effectiveness of the isolation system. This paper presents a …
isolated system for the crusher assembly also results in less transmission of dynamic forces to the substructure. This application will be further illustrated in the case study example No.I which will be explained in the next section. Another cause for the occurance of vibrations in crusher
