简介：Thesubsea动态起床人底(SDRB)是为漂浮的生产站台绳索系统的设备的一重要的片。一结束被连接，带热扩大负担和其它结束的一条僵硬管道，带灵活起床人的动态负担僵硬管道被连接到一个灵活起床人，它的功能因此是在灵活起床人和在海床上修理灵活起床人的僵硬管道之间的一个转变连接。作为一个典型subsea产品，在另一方面，设计将为subsea产品满足标准的要求。由学习尖的干舷和subsea管道的压力analysisphilosophy，为SDRB的尖压力分析的一个物理模型和过程被建立了。负担被考虑了的不利设计的条件，和从僵硬管道和动态负担灵活性的静态的负担的联合也被优化了。并且在为有检查规则的尖应力的AMSE，DNV和API标准之间的比较分析被做了。因为SDRB属于subsea管道终端产品，DNV标准的使用尖应力被推荐检查它的进程。最后，这个过程SDRB的尖应力被计算了，并且结果证明夹克衫管子和SDRB的搬运人管子压力处理尖当whole.The舱壁不能被在详细分析使用FEA软件ANSYS的AutoPIPE软件精确地模仿，满足DNV标准，但是检查结果将仍然满足DNV标准的要求。

简介：一个适应neuro模糊的推理系统(ANFIS)被介绍预言横梁的动态行为。轴的力量和大排水量的效果在分析被考虑。为横梁的动态特征的测试的一个数据库从试验性的测试被开发。为单个、多重步的横梁的非线性的颤动力量的回答从有限元素方法被计算(女性)，为比较的试验性的测试和neuro模糊的模型。neuro模糊的模型为神经网络和模糊逻辑的联合提供一个一般框架。它与合并真实世界的系统的模糊性质的更多的选择是更灵活的并且是为横梁的动态特征的一个有用评价工具。因此，ANFIS能是为受到轴的负担和大排水量的多重步的横梁的动态行为分析的一个有用工具。

简介：作为与不同焊接不规则通过一个磁道的车辆，磁道部件的动态性能被使用acoupled车辆鈥搕rack模型详细调查。在模型，车辆与自由的35个学位作为一个多身体系统被建模，并且一根Timoshenko横梁被用来为被睡眠者分离地支持的栏杆建模。在课程模型，睡眠者为他们的垂直、侧面、滚动的运动作为僵硬身体财务被建模并且假定以经常的速度向后移动模仿以一样的速度沿着课程跑的车辆。在联合车辆和课程动力学的学习，Hertizian接触理论和理论由沈鈥揌edrick鈥揈l建议分别地，家族被用来计算正常并且爬在车轮和栏杆之间的力量。在正常力量的计算，正常接触僵硬的系数被车轮和栏杆表面的短暂接触状况决定。在蠕动的计算，侧面，栏杆的连接运动和在在他们的普通正常方向的车轮和栏杆之间的相对速度等于零的事实同时被考虑。车辆和磁道的运动方程借助于一个明确的集成方法，栏杆焊接不规则作为垂直偏差由一些理想的余弦函数描述了的本地轨道在被建模被解决。不规则的火车速度，轴负担，波长和深度的效果，和在一个睡眠者的焊接中心位置在装载的车轮鈥搑ail影响上跨越被分析。获得的数字结果是极大地在引起由的焊接栏杆侧面不规则的忍耐设计有用在栏杆焊接和轨道维护以后磨手。关键词栏杆焊接-不规则-车辆鈥搕rack联合动力学这个工程被中国(2007CB714702)和中国(50821063，50675183和50875221)的国家自然科学基础的国家基本研究节目支持。
