| 4. | Growing attention has been paid to it from researchers and institutes in this field . until now , the major classification societies have already released their fatigue assessments notes 目前,世界上各主要的船级社均发布了自己的结构疲劳评估规范,作为船舶疲劳评估的指导性文件。 |
| 5. | In the paper , a fatigue assessment and evaluation procedure is developed based on the introduction of general fatigue analysis procedure of ship hulls and in detail discussion of simplified fatigue analysis of oil tanker hulls 本文在介绍船舶疲劳强度分析一般方法的基础上,详细讨论了油轮疲劳分析和计算的程序,开发了相应的分析软件。 |
| 6. | Tanker operators can take advantage of the results of the procedure to determine whether the tanker is to be disposed or repaired or just let it be . the oil tanker hull fatigue assessment and evaluation procedures , implementations and illustrations are presented 论文从航海角度对油轮的疲劳累积过程进行了讨论,对油轮实际营运中对疲劳累积损伤的理解和预防有一定的指导意义。 |
| 7. | The prime goal of this paper is to conduct the fatigue analysis for certain type of structural details of 12300t ro / ro vessel by means of three different approaches stated in dnv classification notes " the fatigue assessment for ship structures " and contrast the results from the three different methods . firstly , the key points of dnv fatigue assessment are addressed , and then the fatigue strength of some nodes concerned is conducted using the simplified analysis provided by dnv fatigue assessment rules . 本文以dnv疲劳评估规范为指导,以12300吨滚装船为依托,探讨了dnv疲劳评估规范中不同方法之间的差异,其主要内容包括: 1 、对dnv疲劳评估方法的要点做以说明,利用dnv疲劳评估文献提供的简化方法对感兴趣的节点进行疲劳评估。 |
| 8. | But due to the complexity of factors influencing fatigue performance , such as wave load and pressure from cargo , the combination of different stress components , stress concentration of local structure details , mean stress and the corrosive environments , etc , there are different specifications with varying classification societies , so it will lead to the diversity of results from different fatigue assessment methods 但是,由于影响结构疲劳性能的因素十分复杂,如波浪载荷和局部的货物压力,各种应力成分的组合,结构的局部细节应力集中,平均应力的影响,结构分身所处的腐蚀环境等等,所以各个船级社有关的规定也不一样,这样必然造成各个评估方法之间的差异。 |
| 9. | To provide a practical tool for fatigue assessment , this approach is based on the so - called simplified fatigue analysis with the assumption that the long - term stress histogram of the hull structure follows the weibull probability distribution , the s - n curves used in the assessment and evabatbn are the basic design - n curves for non - nodal johts " issued by den ( department of energy of united kingdom ) , combining with computer technology the assessment procedure is programmed , which will indicate the fatigue damage condition and degree of technical status of tanker hulls 在中国船级社( ccs ) 《船体结构疲劳强度指南》和美国船级社( abs ) simplifiedfatigueanalysis的基础上,根据对油轮结构特点和货载特点的分析,讨论了油轮船体疲劳损伤的影响因素,讨论油轮疲劳强度计算方法和计算程序,引入模糊质量评级的方法,建立油轮疲劳损伤评估模型。结合先进的计算机技术,编制出油轮疲劳分析程序,采用典型实船资料,对其疲劳状态进行评估,结果与实际情况比较吻合,表明该程序具有一定的合理性,可作为油轮船公司评价油轮技术状态时在疲劳损伤方面的参考。 |
