“…Simulink is capable of building simulation models using the graphical interface and the so-called blocks. Simulink is mainly used (due to the fact that it enables continuous simulations) in digital signal processing, analysis of electrical circuits and control theory [26][27][28][29][30]. The created models were based on calculations and the kinematic analysis.…”

The main objective of the study was to develop a simulation model for the operation of the T-214 CYKLOP grapple loader using the MATLAB package. The created model allowed assessment of the behaviour of the real object in the operating conditions under variable loads and in the system overload. The simulation of the boom operation was carried out in four combinations: (1) at power take-off speed = 1000 rpm without load and (2) at 1000 kg load, (4) at power take-off speed = 540 rpm without load and (4) at 1000 kg load. The results show that the system works properly. The correct functioning of the system is evidenced by the fact that changes in force and acceleration occur on both pistons when only one of the cylinders is operating (the cylinder at rest acts as a shock absorber for the forces resulting from the inertia of the arms and the load). Apart from the increased forces on the pistons of the hydraulic cylinders, the additional load resulted in a slight reduction in acceleration values and an increase in the time needed to change the arm tilt angles.

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.

Wind turbines are widely used for conversion of the wind power into mechanical energy. The failure of the blade during operation is a common phenomenon which can lead to the degradation of the power output. Modeling and analysis of wind turbine blade is critical for the design and safe and efficient operation. In this study, a one-way coupled Finite Element (FE) scale model of RM1 SAFL turbine is developed to simulate structural integrity and deformations in the blades. The study is primarily focusses on the strength and deformation of the blades under varying wind speeds ranging from 5 m/s to 30 m/s. The wind turbine blades were modelled from aluminum alloy and unidirectional carbon reinforced composite (epoxy carbon). The results obtained from numerical simulation demonstrated higher stresses and blade tip deformation in blades from composite compared to aluminum AL 6061 alloy. Maximum displacements were calculated at the tip of blades and were well under the threshold level. The maximum stress intensity was found in the center of the blades. On the basis of the current geometry, modal analysis of turbine blades was performed and benchmark cases for the dynamic response were investigated. The natural frequency for aluminum alloy was calculated to be almost three time higher than of composite material structure. The modal in case of composite material was approximately 35% of that obtained using aluminum alloy. This study suggests further analysis to predict surface integrity of the turbine blades under more volatile wind conditions
