This study presents a combined control strategy for electrohydraulic shaking table (EST) systems. The position frequency bandwidth of the EST system is so low that it results in a worse tracking accuracy during seismic tests, particularly when the frequency bandwidth of the desired position signal exceeds the frequency bandwidth of the EST ...

The shaking tables that are used in earthquake engineering are normally driven by hydraulic actuators, which require high maintenance and operation costs. In some studies, when it is only desirable to conduct small-scaled model tests, a pneumatic shaking table can be considered as an alternative to a hydraulic shaking table. This paper …

FL shaking tables for the upgrading of Knelson concentrates, with newer designs that have been engineered to improve recovery.

Currently the bandwidth and accuracy of shaking tables is such that earthquake motion often cannot be replicated with the desired fidelity. A new model-based motion control method is presented for multi-axis shaking tables. The ability of this method to decouple the control axes is demonstrated.

Adjacent to the shake tables, a large reaction wall equipped with dynamic actuators allows the application of computer-simulated forces on shake table-mounted substructures, thus simulating the reaction of the entire structure (Real …

The development of shaking tables–A historical note. The earliest known shaking table, driven by hand‐power, was constructed in Japan at the end of the 19th century. At the beginning of the 20th century developments had moved to the Stanford University in the U.S. with the introduction of an electric motor to produce a more refined ...

The major advantage of shaking tables is the fact that separation can be observed in real-time. This enables changes and allows adjustments to be made, hence improving the next separation process.

Abstract and Figures. Among all gravity concentration methods, Shaking-table is the most effective one from the metallurgical point of view. In this study, Shaking-table was used for concentrating ...

The feedforward minimal control synthesis algorithm and its application to the control of shaking-tables

Abstract Since the early 1990s, research in Europe, the Far East, and America on the control of shaking-tables for seismic investigations has been made all the more urgent, following a series of catastrophic earthquakes across the globe. The fidelity of the results from shaking-table tests, on which many designs of earthquake-proof …

The leading problems related to the main testing methodologies (static, pseudo-dynamic, and shaking table) are identified and discussed. The advantages and disadvantages of each one are also highlighted. Moreover, a brief presentation of the centrifuge tests is introduced and, finally, the future developments needed are identified.

A new Kalman lter approach for structural parameter tracking: application to the monitoring of damaging structures tested on shaking-tables

The adaptive iterative learning control method for electro-hydraulic shaking tables based on the complex optimization algorithm was proposed to overcome the potential stability problem of the traditional iteration control method. The system identification precision's influence on convergence was analyzed. Based on the real …

A new Kalman filter approach for structural parameter tracking: Application to the monitoring of damaging structures tested on shaking-tables

The shaking table is a very important device for simulating earthquakes in the laboratory and provides an accurate method for measuring structural responses under seismic conditions [ 1 – 4 ]. With the development of the shaking table, it has become an effective measure for studying the elastoplastic seismic response of structures [ 5 ].

Large systems such as tall buildings, long-span bridges, or SFSI are difficult to test on shake tables

This comprehensive guide delves into the history, mechanics, and applications of gold shaking tables, shedding light on their pivotal role in the modern mining industry.

The shaker table shown is a standard 2 right-hand version. It is a mechanically operated reciprocating action table, consisting of a self-oiling enclosed type of head motion, a partly riffled rectangular deck, and an understructure with a …

Shake tables are available in "single-axis", "bi-axial", or "multi-axis" options, designed as either servo-hydraulic or servo electromechanical driven. "Rota Uniaxial Shake Tables" actuate structures or components mounted on the table by applying linear uniaxial acceleration. This product is a medium-sized uniaxial earthquake simulator that ...

Abstract—Shake tables provide a critical tool for simulating earthquake events and testing the response of structures to seismic forces. However, existing shake tables are either ex-pensive or proprietary. This paper presents the design and implementation of a low-cost, open-source shake table named Shakebot for earthquake engineering research and …
