Response study of tower crane and elastic plate under dynamic complicated excitation
Fu Liu, Haopeng Chen
TL;DR
This paper studies how tower cranes and elastic plates respond to complex dynamic forces, focusing on vibration behavior and stability under emergency braking.
Contribution
A novel spatially coupled dynamics model is proposed to analyze tower crane and elastic plate responses under dynamic excitations and emergency braking.
Findings
Emergency braking time exceeding 1.5 seconds minimizes system vibration.
Kurtosis, Factor, and Skewness Values are highly sensitive to plate and swing angle dynamics.
Frequency Center, Root Mean Square Frequency, and Frequency Standard Deviation show distinct sensitivity patterns to system responses.
Abstract
Structural vibration will inevitably occur under the dynamic complicated excitations in tower crane and elastic plate system. The continuous nonlinear vibration would lead to the deterioration of the coupling state of the responses of the tower crane and the elastic plate system. This, in turn, impacts the operational stability and reduces the service life of components. Consequently, there has been scant research on response calculation of the structure in a tower crane and elastic plate system when considering such dynamic and complex excitations. To address this gap, this paper employs a spatially coupled dynamics model of the tower crane and the plate, covering the acceleration stage, the constant speed stage, and then the deceleration stage. This model incorporates typical air resistance, the Lagrange equation, and the calculation equations based on the Reissner plate theory.…
