A low-cost shake table with the dimensions of 1.5 m × 2.0 m was built for 45,000 USD [15], and a shake table with a larger size of 2.5 m × 3.5 m was built for slightly less than 250,000 EUR [16]. Hence, even for the cheapest shake tables, the …
Therefore, a low-cost shake table named SARSAR with Arduino microcontroller boards has been developed for earthquake simulations. The horizontal components of the acceleration records obtained from past earthquakes are scaled and transferred to the shake table by developing software programs using an Arduino DUE board. For …

This study presents the results of a large-scale experimental investigation of sustainable and low-cost seismic isolators based on deformable rubber spheres rolling on concrete surfaces.
TeMs were prepared by irradiation with 84 Kr 15+ ions with an energy of 1.75 MeV/nucleon and ion fluence of 4.3·10 7 ion/cm 2, 12 µm thick PET films using the DC-60 accelerator in Astana branch of Nuclear Physics Institute. Then membranes with certain pore diameters were obtained by means of photosensitization for 30 min from …
Hence, during the last decades many shake tables in different scales have been constructed and developed mainly in Japan, USA, and Europe.1,2 The shake tables are classified as small (smaller than 3 m × 3m ), medium (from 3 m × 3m to 9 m× 9m ) and large (greater than 9 m × 9 m) tables. 3 Large shake tables are valuable tools for ...
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 expensive or proprietary. This paper presents the design and implementation of a low-cost, open-source shake table named Shakebot for earthquake engineering …
2.1 Main Components of Shake Table 2.1.1 Motor. It usually has two basic parts, an outer stationary stator having multiphase coils supply which uses alternating current to produce a rotatory magnetic field, and to the relative mechanical rotation of the output shaft, an insider rotor attached to the output shaft for producing a rotating …
the design process of shake tables have been focused on cost-effective, state-of-the-art small-sized unidirectional shake table facilities. For instance, Moncarz4 and …

2.3. Water content. The water content of hydrogel is an important parameter affecting its performance. The hydrogel was placed in a weighing bottle in an oven at 105 °C for 24 h and the water content (%) was calculated according to the following equation (Fan et al., 2013): (1) Water content = g 1 − g 0 g 0 × 100 where g 1 is the weight of the …

The cost of shake table is very high and it is difficult for the institutes to acquire such facilities. Based on this fact, an effort has been made to fabricate a low cost shake table with required specifications to test models in Earthquake Engineering Laboratory along with a LVDT based instrumentation setup.
To complete this validation, we designed and built a low-cost, small-scale shake table, called Shakebot (Fig. 1). The Shakebot provides a reverse method for simulation validation. Physics engines have been used for robotic de-velopment.

For some twenty years, Quanser Shake Tables are helping civil engineering students grasp complex concepts of structural dynamics and earthquake engineering more quickly and thoroughly. Engaging, hands-on experiments allow them to leap past dry theory and 'experience' an earthquake in safety of the lab. Inspired by Dr. Shirley Dyke, the …

under earthquake conditions. TABLE I compares existing tabletop shake tables and the Shakebot. Existing tabletop shake tables are comparatively expensive [14, 15, 20] or only allow a fixed ground motion pattern [16]. None of the existing tabletop shake tables have open-sourced their hardware. Another limitation of existing shake tables is

The Shake Table II consists of a top stage driven by a powerful motor that allows it to achieve an acceleration of 2.5 g when loaded with a 7.5 kg mass. The stage has a total travel of 15.2 cm and rides on two ground-hardened metal shafts using linear bearings, which allows for smooth linear motion with low path deflection.
