Abstract
We obtained the vibration response of the GKZ17 overhead working truck under normal wind load through field measurement made for four operating conditions. In the test, a vibration test system was arranged on the working platform of this overhead working truck. The time-domain and frequency-domain characteristics of displacement and acceleration were obtained from analysis on the measured data. The results show that when the wind direction is perpendicular to the working plane, the downwind response is dominated, but the crosswind response is also large and shall be highly valued; and when the wind direction is parallel with the working plane, the downwind wind-induced vibration response is small and the crosswind response is dominated. The frequency domain analysis indicates that this overhead working truck is more sensitive to low-order frequencies.
