Position Control of Heave Compensation for Offshore Cranes Based on a Particle Swarm Optimized Model Predictive Trajectory Path Controller

Journal of Marine Science and Engineering, 2022
The wave compensation system can be very useful in several naval applications. It can greatly reduce the relative irregular motion between the two ships when replenishment operations are performed, or between the ship and the offshore platform, which is ...

Study of the dynamics of the movement mechanism of an overhead crane as a complex electromechanical system

Вісник Східноукраїнського національного університету імені Володимира Даля, 2022
The article studies the dynamics of the crane movement mechanism to take measures for their reliable operation and reduce the wear of movement mechanisms. For this, the following assumptions are accepted: transverse motion is not considered, the dynamics of engines and electric drive is not considered; the crane is presented in the form of a seven–mass

Dynamic analysis of the joint movement of the hoisting and slewing mechanisms of a boom crane

Naukovij žurnal «Tehnìka ta energetika», 2023
To increase the productivity of boom cranes, the operation of individual mechanisms is combined. At the same time, dynamic loads on structural elements, drive mechanisms and loads on a flexible suspension increase, which reduces the reliability of crane operation and increases energy losses.

Analisys of experimental studies of optimal control of tower crane slewing and trolley movement mechanisms

Naukovij žurnal «Tehnìka ta energetika», 2020
The article analyzes the quality of the implementation of the optimal laws of simultaneous motion of the tower crane slewing and the trolley movement mechanisms. The estimation was carried out according to the maximum and root-mean-square values of the deviations of the theoretical and experimental characteristics.
