标准范围

ISO 20283-2:20 08给出了指南，并规定了测量、诊断评估和报告由推进装置激发的船舶结构振动的要求和程序。结构振动可以是全局的或局部的。这里，主要处理全球振动。从可居住性的角度来看，甲板结构的局部振动在ISO 6954中得到了处理。导致疲劳损伤的局部振动的发生是罕见的，并且与单个配置密切相关。因此，在ISO 20283（所有部分）的范围内，没有提供测量此类振动的一般指南。作为参考，提供了一些关于局部结构振动的结构设计的基本信息。ISO 20283-2:20 08不考虑瞬态船舶振动现象，例如。g.，因为砰的一声而兴奋。即使扭转轴或曲轴振动在某些情况下可能引起相关的结构振动，这里也不考虑它们。在这方面，可以参考相关的分类规则和ISO 20283-4。

ISO 20283-2:2008 gives guidelines, and specifies requirements and procedures for the measurement, diagnostic evaluation and reporting of structural vibration of ships, excited by the propulsion plant. Structural vibration can be of global or of local nature. Here, primarily global vibration is dealt with.Local vibration of deck structures from a habitability point of view is dealt with in ISO 6954. Occurrence of local vibration leading to fatigue damage is rare and strongly related to the individual configuration. Therefore, no general guideline for the measurement of such type of vibration is provided within the scope of ISO 20283 (all parts). For reference, some basic information regarding the design of structures with respect to local structural vibration is provided.ISO 20283-2:2008 does not consider transient ship vibration phenomena, e.g., as excited by slamming.Even though torsional shaft or crankshaft vibration may in some cases cause relevant structural vibration, they are not considered here. In this connection, reference can be made to the relevant classification rules and ISO 20283-4.
