多途信道短慕线时间反转聚焦研究(英文)

The existence of a multi-path channel under the water greatly decreases the accuracy of the short baseline positioning system.In this paper,the application of a time reversal mirror to the short baseline positioning system was investigated.The time reversal mirror technique allowed the acoustic signal to better focus in an unknown environment,which effectively reduced the expansion of multi-path acoustic signals as well as improved the signal focusing.The signal-to-noise ratio(SNR) of the time reversal operator greatly increased and could be obtained by ensonifying the water.The technique was less affected by the environment and therefore more applicable to a complex shallow water environment.Numerical simulations and pool experiments were used to demonstrate the efficiency of this technique.     

不同状腿结构的自升式平台对比分析(英文)

The jack-up unit is one of the best drilling platforms in offshore oil fields with water depth shallower than 150 meters.As the most pivotal component of the jack-up unit,the leg system can directly affect the global performance of a jack-up unit.Investigation shows that there are three kinds of leg structure forms in the world now:the reverse K,X,and mixing types.In order to clarify the advantage and defects of each one,as well as their effect on the global performance of the jack-up unit,this paper commenced to study performance targets of a deepwater jack-up unit with different leg systems(X type,reverse K type,and mixing type).In this paper a typical leg scantling dimension and identical external loads were selected,detailed finite element snalysis(FEA) models were built to simulate the jack-up unit’s structural behavior,and the multi-point constraint(MPC) element together with the spring element was used to deal with the boundary condition.Finally,the above problems were solved by comparative analysis of their main performance targets(including ultimate static strength,dynamic response,and weight).

船模在简谐激励存在时的运行模态分析(英文)

A ship is operated under an extremely complex environment, and waves and winds are assumed to be the stochastic excitations. Moreover, the propeller, host and mechanical equipment can also induce the harmonic responses. In order to reduce structural vibration, it is important to obtain the modal parameters information of a ship. However, the traditional modal parameter identification methods are not suitable since the excitation information is difficult to obtain. Natural excitation technique-eigensystem realization algorithm (NExT-ERA) is an operational modal identification method which abstracts modal parameters only from the response signals, and it is based on the assumption that the input to the structure is pure white noise. Hence, it is necessary to study the influence of harmonic excitations while applying the NExT-ERA method to a ship structure. The results of this research paper indicate the practical experiences under ambient excitation, ship model experiments were successfully done in the modal parameters identification only when the harmonic frequencies were not too close to the modal frequencies.

Simulating an underwater vehicle self-correcting guidance system with Simulink

Underwater vehicles have already adopted self-correcting directional guidance algorithms based on multi-beam self-guidance systems,not waiting for research to determine the most effective algorithms.The main challenges facing research on these guidance systems have been effective modeling of the guidance algorithm and a means to analyze the simulation results.A simulation structure based on Simulink that dealt with both issues was proposed.Initially,a mathematical model of relative motion between the vehicle and the target was developed,which was then encapsulated as a subsystem.Next, steps for constructing a model of the self-correcting guidance algorithm based on the Stateflow module were examined in detail.Finally,a 3-D model of the vehicle and target was created in VRML,and by processing mathematical results,the model was shown moving in a visual environment.This process gives more intuitive results for analyzing the simulation.The results showed that the simulation structure performs well.The simulation program heavily used modularization and encapsulation,so has broad applicability to simulations of other dynamic systems.

一种改进的海洋平台结构损伤诊断方法研究(英文)

In the exploitation of ocean oil and gas, many offshore structures may be damaged due to the severe environment, so an effective method of diagnosing structural damage is urgently needed to locate the damage and evaluate its severity. Genetic algorithms have become some of the most important global optimization tools and been widely used in many fields in recent years because of their simple operation and strong robustness. Based on the natural frequencies and mode shapes of the structure, the damage diagnosis of a jacket offshore platform is attributed to an optimization problem and studied by using a genetic algorithm. According to the principle that the structural stiffness of a certain direction can be greatly affected only when the brace bar in the corresponding direction is damaged, an improved objective function was proposed in this paper targeting measurement noise and the characteristics of modal identification for offshore platforms. This function can be used as fitness function of a genetic algorithm, and both numerical simulation and physical model test results show that the improved method may locate the structural damage and evaluate the severity of a jacket offshore platform satisfactorily while improving the robustness of evolutionary searching and the reliability of damage diagnosis.     

Analysis of solution findings in the conceptual design of function structures

In the conceptual stage the function design process is realized by the computer aided application. After surveying on the function specification methods and the function modeling, a computer aided function design environment is analyzed. Subsequently based on a module library and principle catalogue, a solution finding process as a part of conceptual design is proposed for a creative design. In addition, a search algorithm to find the solution of adaptable function structure is also discussed. The concepts proposed in this paper can support the subsequent design stages, especially simulation for checking the function structure defects.     

用于海船精确驾驶的控制率动力修正研究(英文)

The objective of this work is the analytical synthesis problem for marine vehicles autopilots design.Despite numerous known methods for a solution,the mentioned problem is very complicated due to the presence of an extensive population of certain dynamical conditions,requirements and restrictions,which must be satisfied by the appropriate choice of a steering control law.The aim of this paper is to simplify the procedure of the synthesis,providing accurate steering with desirable dynamics of the control system.The approach proposed here is based on the usage of a special unified multipurpose control law structure that allows decoupling a synthesis into simpler particular optimization problems.In particular,this structure includes a dynamical corrector to support the desirable features for the vehicle’s motion under the action of sea wave disturbances.As a result,a specialized new method for the corrector design is proposed to provide an accurate steering or a trade-off between accurate steering and economical steering of the ship.This method guaranties a certain flexibility of the control law with respect to an actual environment of the sailing;its corresponding turning can be realized in real time onboard.
