In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...

Abstract In the past few decades, high-speed trains have witnessed tremendous and vigorous development with appearance of oil crisis industrialization, which became a significant trend in transportation industry world over. With increase railway mileage, amount train has grown sharply, service life increased gradually components vehicle traction system become worn aged as result. Therefore, adv...

The high speed train control system is a typical hybrid system, which not only contains a continuous evolution process (train position and speed), but also the discrete event between subsystems. Although some formal methods like HUML, HA and DL have already been used in modeling and verification train control systems, they are not good at describing communication behaviors which are in the inte...

The electromagnetic suspension high-speed maglev train system uses long-stator linear synchronous motors (LLSMs) as levitation and traction mechanisms. In this paper, the modeling simulation of power supply for are performed. models include transformers, converters, variable-length cables LLSMs both two sides ends; meanwhile, corresponding control segmented strategies, including two-step method...

The next generation high-speed train system, HEMU-400X, has been developed in Korea since 2007. HEMU-400X means High-speed Electric Multiple Unit – 300 experimental. Objectives of HEMU-400X project is development of next generation high-speed electric multiple unit with maximum operation speed 370km/h and maximum test speed 400km/h, energy efficiently and environment friendly. At present, the d...

Abstract Dynamic calculations of train crossing railway bridges must be carried out in Europe accordance with current valid standards for both new and existing bridges. The high‐speed load model (HSLM) trains to used are defined the Eurocode, denoted as HSLM‐A1 ‐A10. In near past, results gained from these dynamic have shown, that HSLM do not cover bridge vibration response level certain real o...

mobile robot navigation is one of the basic problems in robotics. in this paper, a new approachis proposed for autonomous mobile robot navigation in an unknown environment. the proposedapproach is based on learning virtual parallel paths that propel the mobile robot toward the trackusing a multi-layer, feed-forward neural network. for training, a human operator navigates themobile robot in some...
