29、rocating internal combustion engine driven alternating current generating sets Part 9: Measurement and evaluation of mechanical vibrations 1 Scope This document describes a procedure for measuring and evaluating the external mechanical vibration behaviour of generating sets at the measuring points s
30、tated in this document. It applies to RIC engine driven a.c. generating sets for fixed and mobile installations with rigid and/or resilient mountings. It is applicable for land and marine use, excluding generating sets used on aircraft or those used to propel land vehicles and locomotives. For some
31、specific applications (essential hospital supplies, high rise buildings, etc.) supplementary requirements may be necessary. The provisions of this document are intended to be regarded as a basis for such applications. For generating sets driven by other reciprocating-type prime movers (e.g. sewage g
32、as engines, steam engines), the provisions of this document are intended to be regarded as a basis for such applications. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

39、f a classification society, the additional requirements of the classification society shall be observed. The classification society shall be stated by the customer prior to placing the order. For a.c. generating sets in unclassified equipment, such additional requirements are in each case subject to
40、 agreement between the manufacturer and customer. 5.2 If special requirements from regulations of any other authority, e.g. inspecting and/or legislative authorities, are required to be met, the authority shall be stated by the customer prior to placing the order. Any further additional requirements
41、 shall be subject to agreement between the manufacturer and customer prior to placing the order. 6 Measuring devices The measuring system shall provide the rms values of displacement and velocity with an accuracy of 10 % over the range 10 Hz to 1 000 Hz and an accuracy of 20 %/+10 % over the range 2
42、 Hz to 10 Hz. These values may be obtained from a single sensor whose signal is either integrated or differentiated, depending on the outcome of the measuring device, to derive the quantities not directly measured, provided the accuracy of the measuring system is not adversely affected. The accuracy
43、 of measurement is also affected by the method of connection between the transducer and the object being measured. Both the frequency response and the measured vibration are affected by the method of attaching the transducer. It is especially important to maintain good attachment between the transdu
44、cer and the point on the generating set being measured when vibration levels are high.2 ISO 2017 All rights reserved BS ISO 85289:2017 ISO 8528-9:2017(E) n r Declared engine speed f Frequency s Displacement t Time v Velocity w Angular velocity x Axial co-ordinate y Transverse co-ordinate z Vertical
