Earthquake Engineering Equipments
Earthquake Engineering Equipments are helpful in the practical study of subjects of earthquake engineering & structural dynamics in Civil Engineering and Machine Vibration analysis in mechanical engineering Curriculum for both undergraduate and graduate programs.
The set of equipment in this catalog are designed to help student as well as professors understand the behavior such as damping, static and dynamic response, resonance condition and amplitude magnification, model of vibration, vibration isolation and absorption etc.
1. Servo Operated Shake table (variable amplitude & frequency)
The shake table is an indispensable testing facility for development of earthquake resistance techniques. A shaking table is a platform exited with servo motor to simulate different types of periodic and random motions, such as artificial earthquakes and other dynamic testing signals of inertia forces, which can be used to simulate different types of motion such as recorded earthquake ground motions, sine sweeps, etc. Shake table test results enhance further the understanding of the behavior of structures and calibration of various numerical tools used for analysis. This facility can be utilized for verification of earthquake resistance buildings, other structures, mechanical components, devices, etc.
A single-axis table is the simplest form of earthquake simulator which is not only useful for many investigations when it is only desirable to excite the specimen in one axis, but also simplifies subsequent interpretation of the results.
