基于刚-柔耦合模型的供弹系统动力学分析

舰炮无链供弹系统对保障舰炮稳定射击、有效拦截目标具有重要意义。为了提高舰炮无链供弹系统的可靠性,有必要分析舰炮在射击过程中供弹系统的动力学特性。文中基于刚柔耦合多体动力学理论,采用一种三维实体造型、有限元分析与多体动力学分析理论相结合的刚柔耦合动力学仿真分析方法,分别建立刚柔耦合动力学模型和刚体动力学模型,得到了不同动力学模型下供弹系统启动和稳定阶段阻力矩的大小,并与试验结果对比。研究结果表明:在启动和稳定运转阶段,刚柔耦合模型阻力矩相比于刚体模型更接近于现场试验结果,且柔性体的变形量与现场实测基本一致;刚体模型仿真结果在稳定运转阶段阻力矩与真实结果相差很大。因此对供弹系统建立刚柔耦合模型的动力学仿真,相比于刚体动力学仿真模型更能准确得到供弹系统相关的动力学特性。

基于多智能体技术的舰炮备品备件配置方法

[目的]备品备件的种类和数量直接影响到舰炮装备的保障能力,由于舰船的空间存储能力有限,通常无法溢出式地携带备品备件。为提高装备的部队级保障能力,提出一种基于多智能体仿真的舰炮装备备品备件资源配置方法。[方法]首先,利用多智能体建模技术模拟舰炮装备的功能结构与运行状态;再结合各单元部件的失效率进行蒙特卡洛重复性仿真试验,同时统计计算备件满足率、备件利用率等相关指标;最后,根据上述指标对备品备件配置方案进行分析与评估,通过多次迭代试验得出最优方案。以单100 mm舰炮为例,通过建立多智能体仿真模型,对其备品备件的配置方案进行评估与优化。[结果]相比于携带7个备件的基础式方案,优化方案的备件携带数量减少了约63%,且备件满足率几乎与基础式方案一致,备件利用率提高到2.5倍。[结论]仿真分析案例验证了所提方法的有效性,可为舰炮装备备品备件配置方案的设计提供参考。

Recent progress on wave induced loading measurements in warships

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.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

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.
