亚洲顶级帆船狂欢节

“普吉泰王杯帆船赛之家”的横幅在KATA海滩Kata Beach酒店随处可见．67岁的荷兰籍船长Edwin说“刚有泰王杯的时候．这里还没有一间酒店．不过你看现在!”从第三届比赛开始,他几乎年年都来参加这个亚洲最大最具影响力的帆船赛事,甚至说不清楚是否为了这个原因．离开了故乡荷兰,定居在普吉。     

打造中国家庭第一用艇——六大首发之R＆R SRC26

“赖仕·雷恩”品牌 随着游艇消费在中国的不断深入,中国的游艇生产厂商的注意力也不断地向核心价值转移,从而促使了许多合作品牌的诞生。“赖仕·雷恩”R＆R SRC26游艇是由国内—流动力制造商春风控股集团与意大利知名游艇企业RANCRAFT YACHT公司联合生产的一款专门针对中国市场的中小型家庭用艇,整船的设计、     

赛道上的“幽灵之子”——帕加尼Zonda R

帕加尼初登超跑舞台是在上世纪90年代末, 以其独一无二的外形和灵敏异常的操控,短时间内便跻身一线行列。 其实,帕加尼车身上的大多数组件都来自于不同国家的不同品牌, 然而就是这样一个“作坊式”的厂家,凭借着纯粹的性格, 创造出世界上别具一格的超级跑车,这其中ZondaR车型,便是纯粹之中的纯粹……     

2010年索马里海盗扣留海员人质过千

对海盗来说,2010年可谓全球范围的“丰收之年”。饱受战争摧残而滋生大量海盗的东非,因600多名船员作为人质扣留而成为大多新闻媒体的头条。国际海事局（IMB）发布的最新一组数据可能还需在未来的几天更新,由于索马里海盗使用了母船,使印度洋季风的影响也失去了效用,船舶被劫持数量仍在增加。     

LR和上海佳豪合作开发“绿色”散货船

英国劳氏船级社（LR）和上海佳豪合作共同完成了一般创新型环保散货船设计,其意义远远超出了预期。这艘新设计的35000dwt散货船,根据该项目的临时数据与IMO的能效设计指数（EEDI）比对后发现,该设计比以前的船舶在环保效率方面提高18％。该＂绿色＂设计在很多重要领域都远远超出既定目标,

两种直接波浪能转换系统性能的比较:阿基米德波浪摆和波能浮筒(英文)

Many wave energy conversion devices have not been well received. The main reasons are that they are too complicated and not economical. However, in the last two decades direct conversion systems have drawn the attention of researchers to their widely distributed energy source due to their simple structure and low cost. The most well-known direct conversion systems presently in use include the Archimedes Wave Swing (AWS) and Power Buoy (PB). In this paper, these two systems were simulated in the same conditions and their behaviors were studied in different wave conditions. In order to verify the simulations, results of the generator of the finite element computations were followed. An attempt was made to determine the merits and drawbacks of each method under different wave conditions by comparing the performance of the two systems. The wave conditions suitable for each system were specified.     

双通线加热的热力学及实验分析(英文)

The present investigation deals with process analysis of oxy-acetylene flame assisted double pass line heating for varying plate thickness. oxy-acetylene flame as the heat source for multi pass line heating to achieve 3-D bending of plates with varying thicknesses was studied. The oxy-acetylene flame was modeled as the moving heat source in the FEM analysis. The transient thermal histories were predicted taking into account the temperature dependent thermo-mechanical properties. A comparative study between single pass and double pass line heating residual deformation was also carried out. The temperature distribution and residual deformations predicted by the numerical model developed in the present work compared fairly well with those of the experimental ones.     

Experimental Investigation of TARMAX Model for Modeling of Hydrodynamic Forces on Cylinder-like Structures

A new approach that models lift and drag hydrodynamic force signals operating over cylindrical structures was developed and validated. This approach is based on stochastic auto regressive moving average with exogenous (ARMAX) input and its time-varying form, TARMAX. Model structure selection and parameter estimation were discussed while considering the validation stage. In this paper, the cylindrical structure was considered as a dynamic system with an incoming water wave and resulting forces as the input a...     

水平对置柴油机的开发

水平对置发动机具备较高的动力性能,同时在配装车辆后,还能使车内空间更为舒适宽敞,同时,柴油机因排放二氧化碳更少而广受关注。为此,日本富士重工开发了配装量产乘用车的水平对置柴油机。该款发动机不仅具备优异的动力输出性能和响应性,而且在低噪声、低振动和低燃油耗方面都获得了不错的成绩。同时,由于配装了带氧化催化器和柴油颗粒滤清器的排气后处理装置及废气再循环冷却器,新发动机的排放水平达到了欧4标准。
