简介：这份报纸为保留深海的钻的系统的车站的系统的评估探讨需要半能沉入水中。把半能沉入水中的配置基于选择的钻，系在的系统用不同系在线材料为水深度的一个范围被分析并且设计。这些是钢电线绳，聚酯绳和HMPE(高模量poly乙烯)。系在的分析在计算机软件包裹竖琴用先进充分联合的时间域分析方法被执行。衍射分析首先被使用包括钻的钻塔，系在的线和起床人解决容器的水动力学性质然后完全的动态系统的运动方程在时间领域被开发并且解决。使用先进分析方法，系在的系统的一个矩阵为用各种各样的系在材料在1000m，1500m，和2000m的水深度操作被开发。系在的系统的开发根据通常采用的绳索设计代码，APIRP2SK和APIRP2SM被进行。新鲜尝试然后被做比较地评估系在的系统特征和全球性能。有用结果以系在的材料被获得了，浇深度，并且给系在的配置的参数调音。结果在华南海环境为深海的系在系统的设计和操作提供深入的卓见。

简介：在长期的rheological砍有半固体合金的实验，粒子变粗将窜改试验性的结果的解释。变粗被shear加强导致的传送对流和粒子的吝啬的尺寸在实验期间显著地被改变。一个简单模型被建立了它考虑传送对流的影响。产生生长法律被简化了因为散开和传送对流统治了生长。生长法律被验证与砍在有A356和听铅合金的一个Searl电流计的实验。实验证明在传送对流下面，生长跟随一条线性时间法律并且率常数取决于shear率的根。试验性的结果的修正被表明获得真粘性功能为一shear跳有A356的实验。

简介：S表面控制器被证明了提供有效运动控制为一自治在水下车辆(AUV)。然而，手工地调整他们的控制参数是困难的。为特别AUV的控制器选择最佳参数是重要挑战。自动化这个过程，一个修改的粒子群优化(MPSO)算法被建议。它基于有免疫力的理论，并且使用了非线性的回归策略让惯性重量优化AUV控制参数。为AUV的一个半物理的模拟系统作为一个平台被开发验证建议控制方法，并且它的结构被考虑。模拟结果显示半物理的模拟站台是有用的，优化算法有好本地、全球的寻找的能力，和方法能可靠地为AUV被使用。

简介：流动和海水汇率为回收并且挖出工作被安排的一个围住半的浅海湾用atwo维的数字模型和一个Lagrangian方法被预言了。流动和强调的材料运输过时的人或物上的风效果，和风的三十年的平均值在数字模拟被考虑了。总体上，甚至在回收并且挖出被进行以后，流动模式看起来类似于原来的国家。然而，直到20%～100%的速度变化出现在构造区域的附近。在强迫的夏天风的情况中，在回收并且挖出，，以后的从71.6%～82.9%的海水汇率增加由particle-trackingmethod显示了。在强迫的冬季风的情况中，相反，海水汇率看起来在自然条件下面是97.2%，但是在回收并且挖出以后稍微减少到93.2%。因此，强迫的风在控制海水汇率起一个重要作用。如果挖出同时与回收被执行，Theseawater汇率被15%进一步改进。这建议挖出的罐头是一个有效工具减轻流动的变化。

简介：一台创新可变僵硬设备基于数字模拟被建议并且调查。设备，叫了一个合拢的可变僵硬弹簧(FVSS)，能广泛地被使用，特别在有适应僵硬的调节集体dampers(TMD)。FVSS的一个重要特征是它的能力通过在它的支持之间的距离的一个小面值硬币改变在更低、上面的界限之间的僵硬。这个特殊特征在更短的时间间隔导致更低的时间落后错误和重新调整。设备的管理方程与类似的元素为对称的FVSS被导出并且简化。这台设备然后被用来控制single-degree-of-freedom(SDOF)象multi-degree-of-freedom(MDOF)一样的结构经由半活跃的TMD的结构。数字模拟被进行为这些结构比较几个控制案例。使它更现实主义，有它的自己的限制的一台真实直接当前的马达没有限制除了一个理想的控制案例被模仿，两个都，结果被比较。建议设备能有效地被用来压制结构的不受欢迎的颤动并且更加与一台被动设备相比改进控制器的表演，这被显示出。
