EQUINE DYNAMICS IN FLOAT TRANSPORT

摘要

The purpose of this study is to design horse floats that minimize vibration transmissionrnfrom the float floor to the horse body. The first stage of the project has been partiallyrncompleted and deals with the measurement of vibration transmission from the floor ofrnhorse floats to near wither positions of horses. A two and a three-horse float were studiedrnwith one horse inside of each float during the time of testing on different road surfaces.rnThe floats were driven over a smooth road, a paved rough road and a gravel road.rnAccelerations were measured in the vertical direction on the float floor, a front footrnfetlock, leg, and just down from the wither. The two frequencies that stand out for bothrnhorses are at 2.5 Hz and 6 Hz. The vibration amplitude at 2.5 Hz measured at the fetlockrnis greater than that measured on the floor. Vibration amplitude decreases from the fetlockrnto the wither by several decibels at both frequencies.
