“…In Equation 13, defining the impact of wind power, area A, on which the force has influence, is often treated as a constant value resulting from the initial position of the load [12,26]. The present paper includes the change of the area caused by both wind power and particular movements of crane's elements, as well as defines the parameter of the effective area A eff .…”

“…Work [9] also performs a sensitivity analysis by tornado diagram and fast nonlinear analysis of container cranes. The influence of external forces, having impact on load-carrying systems was analyzed, inter alia, in Works [10][11][12]. In Paper [11], wind power impact on a container crane located in atmospheric boundary layers was considered, where wind power was measured with the use of a seven-component balance with different wind directions.…”

Impact of Wind on the Movement of the Load Carried by Rotary Crane

This paper considers the coupled kinematic and dynamic models of a mobile crane. A full description of boom and load movement has been provided as a response of the system to the influence of kinematic forces. The linear system model was treated as rigid, and the carried load as a nondeformed static body. To describe the position of said load, Bryant angles were used. The dynamic model includes the impact of external forces (wind pressure) while load carrying and positioning. Algorithm and calculation software were developed to enable dynamic phenomena analysis during both a work cycle and free movement of said load. The initial problem was solved by means of the ode45 calculation procedure in the Matlab software based on the Runge–Kutta 4th Order Method. The work presents exemplary results of load movement simulation with respect to various wind velocities, selected on the basis of guidelines from Poland’s standards regarding safe operation of mechanical equipment.

“…In the literature, several works on the subject of strength analysis, load dynamics or trajectory optimization can be found. Research on transport machines primarily concerns issues related to rotary cranes [3][4][5][6][7][8][9][10], tower cranes [11,12] and gantry cranes [13][14][15][16][17][18][19][20].…”

“…Works [3][4][5] concern modelling of rotary crane load dynamics, taking into account various transport processes and positioning. The load positioning process under the influence of kinematic forcing [3] and the impact of external forces on load deflections during crane working cycle [4] were analysed. The dynamics of the lifted load and mobile crane with consideration of the flexibility of support system on crane stability [5] was also investigated.…”

This work presents the analysis of the load motion during the interaction of wind pressure. The load was treated as a rigid body, and the rope system model as a non-deformed. The influence of effective area of wind pressure on load motion was considered. The theoretical model of load motion was presented, which may be an universal approach for transporting machines equipped with a rope-lifting system. To define the orientation of the movable Cartesian coordinate system related to the load, Bryant angles were used. An algorithm and computational program were developed to allow for analysis of dynamic phenomena. The initial problem was solved with the use of the ode45 calculation procedure in the Matlab software on the basis of the Runge-Kutta 4th Order Method. The obtained results were verified with the experimental ones achieved in the wind tunnel and Tracker program. Numerical calculations using commercial software SolidWorks were also presented. In the experiment, the spatial motion of the load was analysed. Experimental tests were carried out for gust of wind and constant temperature and humidity. In addition, the paper presents the application of the proposed method for a load carried by a rotary crane. After taking into account the control functions resulting from the nature of the work of any machine, the formulated model can be a full description of the carried load motion taking into account external forces.
