为解决海运时海工重大件货物在船上的系固问题,分别介绍了柔性系固、刚性系固和刚柔混合系固3种常见的系固方式,其中刚性系固方式适用于大型海工重大件的系固。基于IMO《货物积载与系固安全操作规则》的系固算法和校核方法进行刚性系固,在系固方案初步可行的基础上利用ANSYS有限元分析软件对刚性系固系统中系固索具和焊缝的应力和变形进行模拟分析,根据分析结果校核系固索具和焊缝的强度,以判定重大件货物运输的可行性和安全性,可为类似重大件货物的运输提供参考。  相似文献

正0引言随着全球经济的快速发展和装备制造业水平的提高,越来越多的货物呈现出大型化和重型化的发展趋势,海上大型设备装置的运输变得愈加频繁。对货物进行有效的绑扎和系固,是保障重大件货物海上运输安全的首要前提。为确保海上货物绑扎系固方案的有效性和经济性,必须对货物的可能受风力进行科学的计算,特别是绑扎系固在甲板表面的重大件货物。风洞试验可为重大件货物提供可靠的风力数据,但是风洞试验周期长、成本高,不适用于海上重  相似文献

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。  相似文献

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.  相似文献

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.  相似文献
