Abstract
This paper presents theoretical considerations and numerical calculations concerning wind influence on the movement of the load during working cycle. During the test, the load is treated as a rigid body. The first part of this work includes the analysis of the aluminium cubical model of the load, which could move only in one plane, striving to increase the stability of motion and prevent vibrations. Numerical analysis was performed in Matlab/Simulink program and compared with experimental results, which were carried out in a low speed wind tunnel equipped with PIV system. The study was carried out for two cases: with and without seeding. The second part of this work includes the application of this research method for analysing the laboratory mobile crane’s duty cycle. Numerical simulations were carried out on a modified simulation model. The sample numerical results present the trajectory and positions of the load carried on the non-deformable rope taking into account the wind influence.
