维修性的定量设计   总被引:5,自引:1,他引:4  
当前很多军事装备的维修性设计尚未认真展开,或者只进行一些定性的维修性设计。完全定量的维修性设计虽然存在较大的困难,但停留在定性的维修性设计上,并不能满足产品的维修性需求。针对当前维修性设计的现状,论述了实现维修性MTTR指标的定量设计方法和程序,借以推动工程中的维修性设计。  相似文献

为了有效评价船舶装备研制单位的可靠性、维修性、保障性(RMs)工程能力,以三角模糊数为理论基础,提出了基于贴近度的RMS工程能力评价方法。首先在分析船舶装备研制单位RMS工作特点的基础上,建立了RMS工程能力评价指标体系。其次通过模糊层次分析法建立RMS工程能力评价指标模糊判断矩阵,应用Yager第三指标原理,对三角模糊数精确化,得出指标权重。然后利用贴近度为测度去评价各评价对象指标性能与理想对象指标性能的贴近程度,得到各评价对象优劣次序。最后结合具体案例验证了方法的有效性。  相似文献

由于维修性越来越受到重视,维修性定量指标已写入了船舶的技术规格书中。对船舶系统的维修性指标如何进行验收,目前还没有一套行之有效的方法。针对船舶的特点,提出了一种适合船舶系统的维修性定量评估方法。该方法采用船舶设备的维修时间数据,经过适当折合后进行船舶系统级平均故障修复时间的评估,并对船舶系统平均故障修复时间区间估计的公式进行了推导,有效解决了船舶系统的维修性指标的验收难题。最后用实例说明该方法的应用。  相似文献

针对传统的维修性设计评价方法仅从维修活动去衡量,无法发现设计因素的薄弱环节的缺陷;从设计参数角度进行维修性设计评估,不能明确表达设计的因素与设计结果之间关系,也无法衡量维修性设计水平的好坏.因此,采用支持向量机回归算法并结合矩阵积和式函数和模糊综合评价建立舰船装备的维修性设计评估模型,通过该模型能综合考虑设计参数和设计结果对维修性设计进行合理评价.根据评价结果,进行方案优选或做出设计改进.  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
