IMPACT OF IRAQI WAR ON ECONOMY

In spite of the strong opposition from the international community, the US and British governments bypassed the United Nations Security Council and started military action against Iraq on March 19. This war will seriously affect the economy of Middle East countries as well as that of the United States itself, further hurting a global economy that is already in decline. It will delay the recovery of the world economy by causing a negative chain re-

2005FIGURES OF WORLD SHIPPING （CHINA）SUMMIT年会人物：SPEECHES EXTRACTED FROM WORLD SHIPPING （CHINA） SUMMIT 2004

China is at a stage which full of crucial strtegic opportunities for its economic develpment.The basic conditions for rapid development have been roughly provided.Omce we take the advantage of this opportunity.the economy will improve. Nevertheless, this period is also one that faces difficulties such as large population, small fund, relatively less resource and worse environment which have caused the serious bottleneck effect. Improperly acting, the development opportunity will probably be missed, thus will lead to the stagnancy or turbulence of the economy. Therefore, it is urgent that we make use of this opportunity to build up a scientific idea of development and change the economic increasing pattem.——Ma Liqiang Deputy Secretary General,National Development and Reform Commission

2005FIGURES OF WORLD SHIPPING （CHINA）SUMMIT年会人物：ROBERT MUNDELL,FATHER OF THE EURO

We successfully held the first ＂World Shipping（China）July 2004.Over 500 delegates attended the Summit,including leading figures from the shipping industry,senior politicians and various industry experts.The Summit received an overwhelming response and was acclaimed as the largest and a top-level Summit in global shipping.Views and opinions expressed at the Summit are still being quoted in the press.The term of ＂China Factor＂created by the Summit,has since been widely quoted as industry-specific term.     

Construction of Logistics Infrastructure in Mainland China

From 1949 to the early 1970s, China was almost a self-sufficient economy, and invested little in transportation infrastructure. “Ihe average invesmaent in transpotation was about 3 percent of ttxal investment (China Statistical Yearbook 1991, 133). “Ihe kilometers of rail tracks barely doubled, the amount of Oared reads increased by only 1.3 times and only thirty new port berths were built. Conversely, freight volumes grew by 21, 34, and 31 times in rail, motor, and waterway,

Analysis of motion on agile shell-feeding system

Since cannon drum of agile shell-feeding system rotates frequently and intermittently, its motion must be steady. Outline of driving cam determines the motion of cannon drum, so it is necessary to select the proper outline of cam. Through analysis of parabolic outline and cycloid outline of the cams, the outline that combines the two curves is obtained. According to the demand of production, the value of the outline is revised, and then the method of fitting curve is used to get the expression of the angle of cam and the displacement of the driven part. Through analyzing the motion of the cannon drum, it is suggested that the angle of the cam is proportion to the displacement of the driven part. The cam with the specially derived outline can move steadily.     

Numerical simulation on truncated oval-nosed projectile penetrating into stiffened plate北大核心CSCD

[Objectives]In this paper, the numerical simulation method is used to study the anti-penetration performance and energy absorption mode of a stiffened plate, as well as the influence of different stiffened bars on the flight attitude of the projectile body.[Methods] Finite element software LS-DYNA is used to simulate the process of a truncated oval-nosed projectile penetrating a stiffened plate, and the results of the numerical simulation are compared with an experiment to verify the reliability of the numerical simulation method. The momentum method and mass equivalence method are used to predict the residual velocity of the projectile, and the applicability of different theoretical methods within different velocity ranges is compared. The deformation energy of different regions of the stiffened plate is then extracted to analyze the influence of the initial velocity of the projectile body on the energy absorption mode of the target plate. Finally, the structure of the stiffeners is changed and the influence of the relative position of the stiffeners on the penetration attitude of the projectile body is analyzed.[Results]The results show that the mass equivalence method is more accurate than the momentum method in predicting the residual velocity of the stiffened plate when the initial velocity of the projectile body is in the range of 300–900 m/s. The ratio of the deformation energy of the stiffened plate to the energy loss of the projectile body decreases with the increase of the initial velocity of the projectile body. The effect of a T-stiffened plate on trajectory is greater than that of a rectangular-stiffened plate.[Conclusions]The related calculation method and research results have certain reference value for research and engineering application surrounding the anti-penetration of stiffened plates. © 2023 Chinese Journal of Ship Research.

CFD simulation of the vertical motion characteristics of the moonpool fluid for the truss spar

The research purpose of this paper is to estimate theimpacts of the parameters of the guide plate on the vertical motioncharacteristics of the moonpool fluid. With the volume of fluid（VOF） method, three-dimensional models of the moonpool fluidmotions of the truss spar platform are established. Simulationresults are then presented for the moonpool forced oscillation byemploying the dynamic mesh method and user-defined functions inFLUENT. The motions of the moonpool fluid and the loads on theguide plates are obtained for both cases of square-ring andcrisscross. The results show that the shape and area of the guideplate at the bottom of the moonpool have a significant impact onthe physical parameters of the moonpool, including the load on themoonpool guide plate, motion form of the moonpool fluid and themass flow rate.     

Analysis of mathematical model for micromechanical vibratory wheel gyroscope

By the sketch of structure of MVWG,the working laws of this kind of gyroscope were explained. To the aid of Euler‘‘s Dynamics Equation,a mathematical model of the gyroscope was constructed, and then by the basic working laws of MVWG the model was simplified. Under the conditions of the three axial direction rotations and general rotation, the mathematical model was resolved. And finally by the solutions, the working laws of the gyroscope, the working disparity among all sorts of gyrations and the influences from the gyrations in the axial directions were analysed.     

舰船刚性阻振质量复合托板隔振特性优化设计(英文)

In considering the theory of structural dynamic optimization design, a design method of the structural style of ship composite brace with rigid vibration isolation mass was studied. Two kinds of structural dynamic optimization formulations minimizing the vibration acceleration of the non-pressure hull on the restraining condition of the gross weight of the ship cabin were established: 1) dynamic optimization of the sectional dimensions of the rigid vibration isolation mass in the composite brace; 2) dynamic optimization of the arranging position of the rigid vibration isolation mass. Through the optimization results, sectional dimensions and the arranging position of the rigid vibration isolation mass with better performance in reducing vibration were gained, and some reference was provided for practical engineering designs as well as enrichment of the design method of a novel ship vibration-isolation brace.     

Scattering of surface water waves involving semi-infinite floating elastic plates on water of finite depth

Two problems of scattering of surface water waves involving a semi-infinite elastic plate and a pair of semi-infinite elastic plates,separated by a gap of finite width,floating horizontally on water of finite depth,are investigated in the present work for a two-dimensional time-harmonic case.Within the frame of linear water wave theory,the solutions of the two boundary value problems under consideration have been represented in the forms of eigenfunction expansions.Approximate values of the reflection and transmission coefficients are obtained by solving an over-determined system of linear algebraic equations in each problem.In both the problems,the method of least squares as well as the singular value decomposition have been employed and tables of numerical values of the reflection and transmission coefficients are presented for specific choices of the parameters for modelling the elastic plates.Our main aim is to check the energy balance relation in each problem which plays a very important role in the present approach of solutions of mixed boundary value problems involving Laplace equations.The main advantage of the present approach of solutions is that the results for the values of reflection and transmission coefficients obtained by using both the methods are found to satisfy the energy-balance relations associated with the respective scattering problems under consideration.The absolute values of the reflection and transmission coefficients are presented graphically against different values of the wave numbers.     

Analysis of deformation of rotor and influence on the performance of gyro based on B-spline wavelet FEM

Some construct characteristics and composing material of the new Gyro＇ s rotor are introduced. Some factors resulting in deformation of the rotor surface are analyzed. Under different loads such as the fo,＇ce of deflecting center, the change of temperature, the fo,ce of pressure and couple factors, the deformation of rotor is analyzed with the wavelet finite element simulation software. The vector distributing map of rotor reformation is given. The deformation resulting from the pressure force of photon is studied. Finally, the influence on Gyro＇ s performance because of anomalous surface of rotor due to deformation of rotor is researched and the result is useful to forecast the performance of the drift of gyroscope. The disturbing moment resulting from the deformation of rotor can be compensated using the mathematic method, and provides an important reference for both design and optimization of the rotor.
