Although the intelligent design system is widely used in modern mechanical products design, the optimization of mechanical products design parameters and the method of knowledge acquisition etc. remain the key factors that restrict the development of intelligent design system. On the basis of analyzing data mining methods and knowledge based engineering (KBE) principles, an information model wa...

Cranes play a very important role in transporting heavy loads various industries. However, because of its natural swinging characteristics, the control crane needs to be considered carefully. This paper presents approach flexible cable system consideration both rope length varying and constraints. At first, from Hamilton's extended principle equations motion that characterized coupled transvers...

The motivation for this thesis resulted from a study of semi-automated rail mounted gantry cranes at an Australian seaport container terminal. The Sequential Ordering Problem with Time Windows (SOP-TW) can arise as a subproblem of these crane operations. The SOP-TW corresponds to the task of scheduling a single crane to move a set of containers, where each container has: a fixed pick-up locatio...

Simulator systems are increasing their potential for training personnel in areas where the risks and the safety tasks at work are very important. Taking into account the fact that practical training and related tasks are one of the most dangerous phases involved in the process of becoming a skilled operator, simulators have been introduced in these areas with a lot of success. The new simulatio...

This paper presents investigations of dynamic behaviour of a nonlinear Gantry Crane System (GCS). The dynamic model is derived using Lagrange equation. Various system parameters of the system are tested to observe the actual behaviour of the dynamic model system. System responses including trolley displacement and payload oscillation are analyzed. Simulation is conducted within Matlab environme...

This paper focuses on the development of minimum time control profiles for point-to-point motion a gantry crane system in presence uncertainties modal parameters. Assuming that velocity trolley can be commanded and is subject to limits, an optimal problem posed determine bang-off-bang profile transition from point rest terminal states with no residual vibrations. Both undamped underdamped syste...
