Quanser Shake Table Used for Validation of Sloshing Research

Free-surface dynamics of liquids in tanks subjected to acceleration - also known as sloshing - is an issue touching on many real life applications, including fluid transportation and shipping, as well as design of vibration absorber devices.

Researchers from the Universidad de Santiago de Chile, Chile, Universidad Nacional del Litoral, Argentina, Pontificia Universidad Catolica de Chile, Chile and Rice University, USA, studied the problem using the finite element analysis, based on solving the Navier-Stokes equations of incompressible fluids using a monolithic solver. To validate the numerical results, the research team used Quanser Shake Table II to control the motion of a rectangular tank with ultrasonic sensors.
Experimental setup with the Quanser Shake Table II loaded with the instrumented tank:
table controllers and ultrasonic sensor
The results of the team's research work was published in the December 2013 issue of the Computational Mechanics journal, in the article titled "Finite element computation and experimental validation of sloshing in rectangular tanks."
