Performance analysis of cargo-handling equipment from a green container terminal perspective

This study employs a green container terminal perspective to compare the performance of four types of cargo handling equipment used in container yards – automatic rail, rail, electric tire, and tire transtainers – based on working efficiency, energy saving performance, and carbon reductions. It is found that automatic rail and electric tire transtainers are the optimal types of green cargo handling equipment.     

新型客车上水单元设备水头损失试验分析

对新型铁路上水设备进行了试验，绘制了给水管、上水设备、水箱注水口和上水管出水口之间位能水头、压力水头和流速水头转化关系的总水头线；经分析得出上水系统水头损失主要是由上水设备引起的，而上水软管缠绕又是其中主要的影响因素；分析了产生水头损失的部件及原因，并提出了在设计、设备制造和运行中减少水头损失、提高上水流量的途径和措施。

重大件货物刚性系固中的外力计算

利用特别设计的支架,将重大件货物固定于支架上,并将货物和支架一起固定于船的承载部位,此种系固方法通常称为刚性系固。刚性系固是海上重大件货物（尤指超长、超宽、超重大件货物）运输安全的必要保证。本文应用船舶耐波性理论和方法,建立了作用于货物单元上运动惯性力的计算公式,从而为货物支架的设计和刚性系固系统的强度校核提供了比较精确和可靠的力学依据。

FPSO货油系统管系应力及泵口载荷的分析改进

货油系统作为FPSO最重要的系统之一,一旦出现故障,会使整个海上油田的生产作业陷入停顿或瘫痪的状态,将造成巨大的经济损失,对其进行应力分析,指导管系布置十分必要。本文以30万吨通用型FPSO货油系统为研究对象,应用CAESARII管道应力分析软件建立分析模型,考虑极端工况的加速度、船体变形和风载荷等,对其管系一次应力、二次应力和泵口载荷进行了分析,并对管系的布置进行了优化,提高了管系布置的效率和准确性,为FPSO其他管路系统及其他船型的管系布置提供参考依据。     

基于1 900 TEU支线集装箱船各种载荷工况下的结构强度分析

对集装箱而言,最大中拱和中垂弯矩均出现在货舱区域,货舱区域船体结构应力水平较大,因此货舱区域的结构强度成为全船结构强度评估的重点。各船级社规范对货舱区域结构强度直接计算作了详细说明_[2,4],略有差别。本文采用有限元软件MSC.PATRAN/NASTRAN,基于CCS规范要求,对1900TEU集装箱船建立舱段有限元模型,进行强度计算及结果分析,完善结构设计,对相关的船舶设计提供一定的参考作用。

充分掌握大型集装箱船在满足船舶规范规定的适航、适货条件（船舶吃水、稳性、强度、系固、安全航行及适货要求）,结合国际及国内有关法规及港口有关规定,提高和改善其装载能力,发挥更大经济效益是值得深入探讨的。     

The development of studying flexible pipe bend reinforced by Kevlar fibers

The flexible pipe bend can not only reduce the structural vibration and fluid noise in pipeline, but also realize the flexible connection of a horizontal line and a vertical line and compensate the displacement of three dimensions produced by the shock or vibration of pipeline in the special situations. Up to now, little attention has been paid to study the flexible pipe bend applied in the pipeline of medium or high pressure, because no appropriate framework materials can be used to reinforce it which must endure the burst pressure higher than 10 MPa. The investigation shows that it is possible to produce the flexible pipe bend of medium or high pressure if such fibers with high performance as Kevlar fibers are used to be its reinforced materials. However, its structural designing theory, manufacturing technology and measuring techniques aren‘t yet perfect and systematic, which leads to the instability of the performance of products. Furthermore, few references about its research can be seen. Therefore, it is necessary to systematically and thoroughly develop the structural designing theory, manufacture technology and measuring techniques of flexible pipe bend.
