Dynamic Analysis and Motion Control of Hydraulic Crane for Men Lifting Using Modeling and Simulations

Abstract

This paper deals with modeling and simulation of Hydraulic crane for load lifting in order to determine its dynamics, methods for lifting control and minimization of oscillations. The proposed procedure is modelling of crane with method of schematic design with inerconnected elements that represents crane parts, and its 3-d visualization. Simulations will be planned and applied for lifting motion of Crane's Boom with hangind load. Dynamic analysis will be carried through simulations and solution of Euler differential equations of second order. Diagrams with results of main dynamic and kinematic parameters will be presented for main parts of crane as the solution results of the analyzed system. Based on these results conclusions will be presented. The aim is to find optimal lifting control process and dynamic behavior of crane which is important for motion planning, failure analysis and safety during work. Analysis will be done using modeling and simulations with computer application MapleSim.

Virtual Testing of Counterbalance Forklift Trucks: Implementation and Experimental Validation of a Numerical Multibody Model

“…Only few studies, to the authors' best knowledge, have aimed at implementing tools to assist the structural design process of forklift trucks [21,22]. Therein, the primary objective was evaluating the dynamic stresses affecting only the loaded mast assembly, during longitudinal motion and lifting maneuvers, by taking into account its compliance.…”

Targeting the user experience in the development of mobile machinery using real-time multibody simulation

“…Conventional forklift simulation methods also focus on the development of the mast design system and do not consider the pulley and chain mechanisms or the realistic UX for the working cycles of the truck in the presence of the lifting loads. 6–14 The real-time multibody forklift model have been studied without discussing the hydraulics, pulley and chain mechanism and mast design system. 25…”

“…Many researchers have employed dynamic simulation models to describe the basic design and operation of machines. [6][7][8][9][10][11][12][13][14] Conversely, the involvement of the UX in the early phase of product development through simulation demands the description and faster computation for all sub-components and mechanisms of the mechanical systems in a realistic working environment. The multibody system (MBS) semi-recursive approach enables solution of the equations of motion of complex systems in real time.…”

The Finite Element Analysis and Geometry Improvements of Some Structural Parts of a Diesel Forklift Truck

“…Bhagat et al [1] developed the CAD model of a translation carriage for reach truck and performed the static analyse of it under various loading and boundary conditions using finite element analysis in ANSYS environment. Doçi et al [2] examined the structural behaviours of forklift under dynamic loadings and specified the parameters that affect the dynamic behaviours of forklift. Meshram [3] developed 3D models for the forklift mast with a change in geometry to perform of structural analysis using finite element method.…”
