Effect of the rope system deformation on the working cycle of the mobile crane during interaction of wind pressure
2020
Abstract This work concerns the analysis of the load motion, taking into account wind pressure and the deformation of the rope system. Disturbances resulting from the physical properties of the linear system are presented. The Kelvin–Voigt model was adopted as the deformable model of the rope system. The carried load was treated as a rigid body. The formulated initial–value problem allows the analysis of load motion during kinematic forcing or its free movement. The wind pressure was included in the analytical model by using the formula for aerodynamic drag. Numerical tests were carried out in conditions resulting from the crane operating standards (ISO 4302).
