船舶和海洋技术 - 关于特定船舶可居住性振动的测量 评估和报告指南

[中文适用范围]： 本文件为满足以下一项或两项条件的船上所有人员的可居住性振动的测量、评估和报告提供了指南： a) 直接耦合的二冲程循环、长冲程、低速柴油机安装固定螺距推进螺旋桨。 b) 甲板室的长度(L) 与其高度(H) 相比受到限制（即甲板室的H 与L 的长细比约为1.0 及以上）。 甲板室长度 (L) 和高度 (H) 的长细比示例见附件 A。 频率范围 1 Hz 至 80 Hz 内的总体频率加权均方根振动值作为不同空间的指导值。 船舶。 本文件适用于预定航程24小时及以上的特定船舶。 本文件规定了通常占用空间内的仪器和测量程序的要求。 它还包含评估船舶振动与宜居性相关的分析规范和指南。 本文件不适用于除发动机控制室外人员不长时间停留的机器处所。 客船和商船上所有人（包括本文件也可能适用的特定船舶）的可居住性振动报告可在 ISO 20283-5 中找到。 本文件既不是补充也不是补充，而是对 ISO 20283-5 的补充。 造船厂可以选择本文件或 ISO 20283-5 应用于任何特定船舶，但应适当考虑船舶的个别设计条件以及建造姊妹船或类似船舶的经验（如果有），并且特定选择应得到商定由船东承接。 对可能导致晕动病的低频船舶运动的评估涵盖在 [外文原描述]： ISO 21984:2018 gives guidelines for the measurement, evaluation and reporting of vibration with regard to habitability for all persons on board ships satisfying one or both of the following conditions: a) 2-stroke cycle, long-stroke, low-speed diesel engine directly coupled to the fixed-pitch propulsion propeller is installed. b) length of deck house (L) is limited as compared with its height (H) (i.e. deck house of around 1,0 and above in slenderness ratio of H to L). An example of length of deck house (L) and its height (H) for slenderness ratio is shown in Annex A. Overall frequency-weighted r.m.s. vibration values in the frequency range 1 Hz to 80 Hz are given as guidance values for different spaces on ships. ISO 21984:2018 is applicable to specific ships with intended voyages of 24 h or more. ISO 21984:2018 specifies requirements for the instrumentation and the procedure of measurement in normally occupied spaces. It also contains analysis specifications and guidelines for the evaluation of ship vibration with respect to habitability. This document is not applicable to machinery spaces, other than engine control rooms, where persons do not stay for prolonged periods of time. ISO 20283‑5 is generally applicable to all ships. Requirements for measurement, evaluation and reporting of vibration with regard to habitability for all persons on board passenger and merchant ships, including specific ships to which this document may also be applicable can be found in ISO 20283‑5. This document is neither complementary nor additional but supplementary to ISO 20283‑5. The shipbuilder can select either this document or ISO 20283‑5 to apply to any specific ship upon due consideration to individual design conditions of the ship and, if any, experience in building sister or similar ships, and that particular selection is intended to be agreed on by the shipowner. The evaluation of low-frequency ship motion which can result in motion sickness is covered by ISO 2631‑1. For the evaluation of the global structural vibration of a ship, however, see ISO 20283‑2.
