Examination of Vibration on the Actual Shell Type Roller Gate

Examination of Vibration on the Actual Shell Type Roller Gate

In some cases of shell type roller gates with a long span, oscillations of gates are seen during small gate opening because of their flexibilty. In order to make clear this phenomenon, for an actual shell type roller gate on a river weir, frequency and accelerations of vertical and horizontal direct...

description In some cases of shell type roller gates with a long span, oscillations of gates are seen during small gate opening because of their flexibilty. In order to make clear this phenomenon, for an actual shell type roller gate on a river weir, frequency and accelerations of vertical and horizontal direction were measured at some points, i. e. center, 1/4 and edge of span with small opening. Range of gate opening which causes oscillations, frequency and mode of oscillation, time series of frequency acceleration and etc. were analyzed.
