A Standalone Vision Sensing System for Pseudodynamic Testing of Tuned Liquid Column Dampers

Abstract EN

Experimental investigation of the tuned liquid column damper (TLCD) is a primal factory task prior to its installation at a site and is mainly undertaken by a pseudodynamic test.

In this study, a noncontact standalone vision sensing system is developed to replace a series of the conventional sensors installed at the TLCD tested.

The fast vision sensing system is based on binary pixel counting of the portion of images steamed in a pseudodynamic test and achieves near real-time measurements of wave height, lateral motion, and control force of the TLCD.

The versatile measurements of the system are theoretically and experimentally evaluated through a wide range of lab scale dynamic tests.
