Thesis (MScEng)--University of Stellenbosch, 2003.<br>ENGLISH ABSTRACT: The aim of this thesis is to investigate the wheel/rail/girder interaction of overhead cranes. Three components of the above mentioned interaction system are considered. • The contact interaction between the crane wheel and the rail and its effects on the rail stresses. • The stress distribution in thin webbed rails and the location of critical stresses in the rail. • The load distribution between the rail foot and the crane girder with the inclusion of elastomeric pads. The steps followed for the purpose of this i

Abstract:

Hoists and cranes exist in many contexts around the world, often carrying veryheavy loads. The safety for the user and bystanders is of utmost importance. Thisthesis investigates whether it is possible to perform fault detection on a systemlevel, measuring the inputs and outputs of the system without introducing newsensors. The possibility of detecting dangerous faults while letting safe faultspass is also examined.A mathematical greybox model is developed and the unknown parametersare estimated using data from a labscale test crane. Validation is then performedwith other datasets to check the

Abstract:

Intermediate diaphragms are invariably included in the design of overhead travelling crane box-girders. This study concerns the influence of these diaphragms and their spacing on the global characteristic behaviour of the girder. In particular the action of internal diaphragms in the control of stresses associated with distortional deformation is investigated. The details and results of experimental tests on scale models of two crane geometries are presented. A method of analysis is developed to describe the distortional deformation of crane box-girder geometries using discrete box section ele

Overhead travelling cranes aid in production by allowing an uninterrupted work process on the ground while heavy loads are moved to their required locations. Various factors need consideration in determining the loads induced by an EOHTC on its support structure. In order to design such a support structure, the designer must understand and take into account the vario

The major shortcoming in the application of fuzzy controller is due to the difficulty of fuzzy rule design. In the thesis, the random optimization algorithm is adopted to search for parameters used in the fuzzy logic controller. Firstly, dynamic equations of a home-made overhead crane system are derived both with Newton’s second law and Lagrange’s method. The correctness is then judged by computer simulations.

碩士<br>國立屏東科技大學<br>車輛工程系碩士班<br>93<br>A crane system is one of the major measures to carry heavy objects or containers on land and in factories. During operation, the acceleration and deceleration of a trolley can make hanging objects sway. This may lead to the break of the cable or dropping of the load and leave people in danger. To avoid these situations and to effectively control the crane systems, this research proposed a sliding-mode-like control method to make the crane system sway with smaller angles and reach the desire position with less time. In this research, the control simulation pa

碩士<br>國立屏東科技大學<br>車輛工程系所<br>96<br>Traditionally, the overhead crane system is always operated by human. In order to reduce the cost of personnel expense, the automatic control of the overhead crane system is developed. In process of the automatic control, the most important issues are high positioning accuracy, short transportation time, small sway angle, and high safety. So that the stabilization control for overhead crane system becomes more and more major. There are many kinds of control schemes in the overhead crane system, and a nonlinear control scheme which includes both the cart motion

The control law includes a model-based friction compensation identified by optimization techniques. The design process is divided into three parts. In the first part, the Simplex optimization algorithm is used to find the optimal control gains while the system is controlled under the torque mode and position and angle tracking errors are used. In the second part, optimal path is searched for also by the Simplex method while the

And then a fuzzy-blended PD controller with optimal reference path is found by parallel genetic algorithms. Finally, the controller is implemented in a dSPACE DS1104 control board for experiments.

Actually, a practical overhead crane system and its fuzzy controller might cost lots money. Therefore, in the experiment class, many students share a overhead crane system leading to less efficiency of learning. Thus, we use C++ language to develop the 3-Dimension overhead crane teaching software with Fuzzy Controller. Every student can learn fuzzy control by adjust the parameters of membership functions and rule base in this software. In this way, students can get the exp

Since the overhead crane system is subject to underactuation with respect to the load sway dynamics, it is very hard to manipulate the crane system in a desired manner, namely, gantry position tracking and sway angle stabilization.

碩士<br>國立臺灣大學<br>機械工程學研究所<br>87<br>This thesis deals with the nonlinear modeling and anti-swing control of an overhead crane including cable dynamics. With fixed length of the rope, a set of nonlinear distributed-parameter equations of motion which allow the payload to swing in the three-dimensional space is derived. A finite-dimensional dynamic model is then obtained via eigenfunction expansion. This finite-dimensional dynamic model is subsequently used in controller design and dynamic simulation. For the point-to-point position control of the payload, the controller design strategy

In order to exploit the readiness of industrial servo motors, the motor drivers were assumed to be set in velocity mode. Besides, Microsoft Kinect sensor was used for the estimation of payload positions to derive the swing angle. The acquiring of swing angle using Kinect introduces significant time delay, approximately 0.23 seconds, which should be counteracted by the controller. A adaptive neural network was develop

The design objective is to resolve issues related to the need for system dynamic models in the design of conventional controllers; for this purpose, a fuzzy logic system was used in the controller’s design. The advantage of fuzzy logic systems is that they provide an effective system architecture, which can be used to process the semantic fuzzy information contained in the human descriptions of a problem.
