游艇码头定位桩桩长的确定方法

针对温州瓯江港区浮式游艇码头在接近35 m淤泥质土的地质条件下全直定位桩桩长确定和地基承载能力的问题,采用数值模拟方法,在波浪力和水流力作用下,对不同定位桩长的码头结构进行三维全尺度数值模拟分析和地基承载力校验,得到不同定位桩长的剪力和弯矩的内力分布特征、桩顶最大位移、桩身最大应力随不同桩长变化趋势。再根据定位桩自重和桩侧土极限侧摩阻力标准值确定桩底应力,与地基承载能力进行对比分析。研究表明,对于类似工程,可采用以地基承载力和桩顶位移为主、以桩身应力控制为辅助的控制方法来确定桩长。

超小水线面船主机舱段结构优化设计

采用MSC. Nastran的静态响应有限元分析的优化方法,对某超小水线面船的主机舱段构件进行优化,降低该舱段的结构重量,增大舱内空间,为整船结构模型计算中构件参数的确定提供了依据。     

小型帆船自适应自动舵

帆船由于其结构的特殊使其动态特性呈严重的非线性，航向很难控制。首先针对一种小型竞赛用的12m长美洲杯赛帆船，从其结构出发建立数学模型，并对该模型进行了开环仿真试验以验证其真实程度。然后利用MATLAB辨识工具在不同的外部条件下得到各具特色的不同模型，由此确认模型参数的巨大变化难以用一个近似于当前运行模式下的线性化模型设计控制器，因而设计了一个采用自适应LQR的自动舵以控制帆船尖不同外部条件下都能保持航向。最后在该模型上作了仿真，取得了较好的效果。

A video-based approach to promote safe driving among foreign visitors to Japan

Recently, the demand for car rentals has been increasing at tourist destinations in Japan due to their convenience and the high degree of freedom they offer. On the other hand, there is a problem of a dramatic rise in the number of traffic accidents involving drivers from countries with different traffic customs and cultures from Japan. In order to examine measures to reduce the traffic accident risk of foreign drivers visiting Japan, an animation video to promote safe driving was created and its educational effects were tested in this article. First, through a driving survey of foreigners and a review of preceding studies, we identified information on Priority, Speed, and Comprehension (PSC) that must be learned by foreign visitors to reduce their accident risk. Next, drawing from the technique of branded contents in order to enhance the effects of educational videos, we created a short video that conveys the PSC philosophy that should be understood for safe driving in Japan. We then tested the educational effects of the video by conducting a survey of Taiwanese people. The results show that strengthening the video's appeal leads to improvements in educational effects and therefore safety awareness. We also realized that the effect was particularly significant among young people in their twenties. Lastly, the rent-a-car businesses evaluated the videos and basing on their input, we summarized effective ways for foreign rent-a-car users visiting Japan to use the video.     

19.8m豪华游艇主尺度确定及主机功率估算

在游艇设计初期,往往因为设计任务书中已知信息较少而难以较准确地确定游艇的主尺度和主机功率。本文以一艘长为19.8m的游艇为例,给出了游艇设计初期只已知排水量、最大航速和总长的情况下各主尺度的确定方法。并结合大隅三彦功率估算方法和作者提出的母型艇系列拟合方法得出主机功率的估算值,为游艇设计中主机选型和成本估算做准备。
