Research ArticleOpen accessEvery word in the titleMinimization of Load Oscillations in Travelling Mechanisms of CranesKamal KhandakjiThe paper presents an analysis of suspended load (cargo) oscillations in traveling mechanisms of cranes. A special control algorithm has been developed in order to get minimum cargo oscillations in minimum transient time. Mathematical model simulating the effect of the suggested control algorithm on cargo oscillations has been developed. Two power electronic circuits applicable for AC drives with three-phase induction … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,672 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMathematical Model of 4-Quadrant DC Electric Drive with 6-Pulse Dual ConverterKosmas ZdrozisMathematical model simulating the operation of DC electric drive hoisting mechanism has been developed. The study illustrates the capabilities of the developed model for investigation both normal and abnormal modes of operation of the converter and the supplying voltage. Large attention was given to the thyristor converter and its firing system so that fast-proceed micro-processes occurring in the converter can … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,001 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuay Crane Scheduling in Container Terminals Using a Hybrid Genetic AlgorithmAidi Sanaa, Torbi Imane, Mazouzi MohamedContainer terminals are crucial nodes within the global supply chain, playing a vital role in the efficient movement of goods. Effective scheduling of Quay Cranes (QCs) is a key factor in maximizing port productivity and minimizing delays. This research investigates the Quay Crane Scheduling Problem (QCSP) using a Hybrid Genetic Algorithm (HGA). The proposed HGA method combines the exploratory power … …Journal of Computer Science, Vol. 21, Issue 1 · 26 Dec 2024 · 6,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometry and Determining the Positions of a Plan Transporter ManipulatorRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The conveyor mechanism (working in a plan) to be presented in this study is a classic case of manipulating conveyor, simply with a single degree of mobility. It is a very common mechanism used in classical mechanics, being encountered at lifting platforms, at handicapped chairs, at cranes, forklifts, automatic machines and machines, or at older steam locomotives where it having … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 1 Jan 2018 · 6,551 accessesView PDFCite
