12、s, vehicles and structures” (Secretariat: DIN, Germany), under German leadership of this project. The responsible German body involved in its preparation was DIN-Normenausschuss Akustik, Lrmminderung und Schwingungstechnik im DIN und VDI (DIN and VDI Standards Committee Acoustics, Noise Control and

13、Vibration Engineering), Working Committee NA 001-03-03-03 (NALS/VDI C 3) Messung und Beurteilung von Maschinenschwingungen. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN shall not be held responsible for identifying any or a

ISO 20816 consists of the following parts, under the general title Mechanical vibration Measurement and evaluation of machine vibration: Part 1: General guidelines 1) Part 2: Land-based gas turbines, steam turbines

17、and generators in excess of 40 MW, with fluid-film bearings and rated speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min and 3 600 r/min 2) Part 5: Machine sets in hydraulic power generating and pump-storage plants 3)1)ISO 7919-1:1996, ISO 10816-1:1995 and ISO 10816-1:1995/Amd.1:2009 have been revised

18、and combined. 2)ISO 7919-2:2009 and ISO 10816-2:2009 have been revised and combined. 3)ISO 7919-5:2005 and ISO 10816-5:2000 have been revised and combined. DIN ISO 20816-1:2017-03 4 Rationale for A.2.2.4 In principle, the following applies: max SA(pp), SB(p-p) S(p-p)max 2 Smax. According to previous

19、 experience, the equation max SA(pp), SB(p-p) = 1,85 Smaxprovides an approximation which is suitable for most orbits of shaft, particularly if orbits are not closed. Smaxis a maximum value shaft vibration relating to the orbit. Thus, information on the time-integrated mean position of the vitration

20、is not necessary. Smaxcan nowadays be determined by microprocess-equipped instruments only using the AC voltage components of the signals of the transducers A and B. The additionally calculated mean value (mean position) is used to set the nominal distance of the transducer and to control the radial

21、 position of the shaft with regard to changes in the load on the bearing, the misalignment and rubbing against the rotor. Amendments This standard differs from DIN ISO 7919-1:1997-08, DIN ISO 10816-1:1997-08 and DIN ISO 10816-1/A2:2010-06 as follows: a) the content of DIN EN 7919-1:1997-08, ISO 1081

22、6-1:08 and OIML R 10816-1:2010 has been revised and combined; b) typical measuring points at the machine housing have been revised; c) normative references have been updated.

41、16-1:2017-03 7 IntroductionMachines are now being operated at increasingly high rotational speeds and loads, as well as more flexible operation at part and full load, and under increasingly severe operating conditions. This has become possible, to a large extent, by the more efficient use of materia

42、ls, although this has sometimes resulted in there being less margin for design and application errors.At present, it is not uncommon for continuous operation to be expected and required for 2 years or 3 years between maintenance operations. Consequently, more restrictive requirements are being speci

43、fied for operating vibration values of rotating machinery, in order to ensure continued safe and reliable operation.This document is a basic document which establishes general guidelines for the measurement and evaluation of mechanical vibration of machinery, as measured on rotating and on non-rotat

44、ing (and, where applicable, non-reciprocating) parts of complete machines, such as shafts or bearing housings. Recommendations for measurements and evaluation criteria pertaining to specific machine types are provided in additional parts of ISO 20816 as they become available as a replacement of the

45、relevant parts of ISO 7919 and ISO 10816. ISO/TR 19201 gives an overview over these and further machinery vibration standards.For some machines, measurements made on non-rotating parts are sufficient to characterize adequately their running conditions with respect to trouble-free operation. There ar

46、e also types of machine, such as steam turbines, gas turbines and turbo compressors, all of which can have several modes of vibration in the service speed range, for which measurements on structural members, such as the bearing housings, might not adequately characterize the running condition of the

47、 machine, although such measurements are useful. Such machines generally contain flexible rotor shaft systems, and changes in the vibration condition can be detected more decisively and more sensitively by measurements on the rotating elements. Machines having relatively stiff and/or heavy casings in comparison to rotor mass are typical of those classes of machines for which shaft vibration measurements are frequently preferred.Vibration measurements are used for a
