16、. 11 Bibliography . 17 BSISO20171:2005iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member b
17、ody interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electro
18、technical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted
19、by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent r
20、ights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2017-1 was prepared by Technical Committee ISO/TC 108, Mechanical vibration and shock. This first edition of ISO 2017-1, together with ISO 2017-2, cancels and replaces ISO 2017:1982, which has been technicall
21、y revised. ISO 2017 consists of the following parts, under the general title Mechanical vibration and shock Resilient mounting systems: Part 1: Technical information to be exchanged for the application of isolation systems Part 2: Technical information to be exchanged for the application of vibratio
22、n isolation associated with railway systems BSISO20171:2005 vIntroduction This International Standard is limited to the consideration of resilient devices. Some suppliers of shock and vibration isolators (resilient mounts) have experience covering a wide variety of applications. In most instances, t
23、hey are willing to use this background information for solving the users problems with isolators. However, it is frequently difficult for the supplier to provide this service, because the customer, the user or the producer of the vibration source or receiver has not furnished sufficient information
24、regarding the application. On the other hand, the user is sometimes handicapped in applying isolators properly because the supplier does not furnish sufficient technical information. Consequently, the users must conduct their own experimental evaluation of the isolator and may unknowingly duplicate
25、work already carried out by the supplier. With some vibration sources or receivers, the producer provides the isolating system. To do that, the producer needs all the information from the customer relating to the future application, site and environment. This International Standard is intended to se
26、rve as guide for the exchange of technical information between the customer, the supplier of resilient devices, and the producer of vibration sources or receivers, as required for their proper application. BSISO20171:2005 1Mechanical vibration and shock Resilient mounting systems Part 1: Technical i
27、nformation to be exchanged for the application of isolation systems 1 Scope This part of ISO 2017 establishes requirements to ensure the appropriate exchange of information between users, manufacturers and suppliers of vibration sources and receivers regarding the application of isolation systems. T
28、he sources and the receivers can be machines, structures, people or sensitive equipment subjected to vibrations and shocks generated by machines, railways, road traffic and other external and internal sources where the vibrations are usually transmitted through the ground to a building. This part of
29、 ISO 2017 is applicable to the use of new products (source or receiver), and can also be applied to previously installed products when the user wishes to solve a newly arisen vibration problem. It is not to be considered as a manual for the design or installation of an isolation system. Examples of
30、elements of vibration isolation are shown in Annex A, for information only. This part of ISO 2017 is intended to provide appropriate responses to questions highlighted by the producer and users (e.g. why, what, when and how to isolate mechanical systems). 2 Normative references The following normati
31、ve documents are indispensable for the application of this document. For dated references only the edition cited applies. For undated references, the latest edition of the referenced document ( including any amendments) applies. ISO 2041:1990, Vibration and shock Vocabulary ISO 9688:1990, Mechanical

34、 an equipment item and its supporting structure to attenuate the transmission of shock or vibration from the equipment to the structure or from the structure to the equipment 3.2 vibration source simple or multiple solid, liquid or gaseous body causing vibration in its environment NOTE This covers s
35、ources such as machinery, traffic, explosions, wave loading and wind loading. 3.3 vibration receiver all structures or elements of structures responding to vibration energy emitted by an internal or external source 3.4 customer user or purchaser of a product (building, machine, etc.) 3.5 producer pa
36、rty constructing or manufacturing a product that needs to be isolated from internal or external vibration 3.6 isolation supplier party responsible for providing and installing an isolation system which will meet the requirements to reduce vibration as agreed upon with the customer NOTE 1 In certain
37、cases, the producer and the supplier may be the same party. NOTE 2 The customer, the producer or the supplier may each mandate subcontractors to execute the work or to purchase elements. From a legal point of view, all three remain responsible in the case of failure of the project. 4 Purpose of vibr
38、ation isolation (why isolate mechanical systems) The purpose of vibration isolation is to protect people and mechanical systems from vibrations and shocks by taking action on the source or the receiver of the vibration. The purpose may include assurance of the following: a) the safety of the industr
39、ial building containing the vibrating equipment itself; b) the safety and comfort of the operators of the vibrating machine; c) the safety and comfort of bystanders near the vibrating machine; d) the security of a building located close to a source of vibration, such as an industrial plant or railwa
40、y; e) the comfort of people in temporary or permanent habitations that may be subject to vibration excitation; f) the security of sensitive equipment in buildings; g) the correct operation of the isolated equipment; h) meeting regulatory requirements. BSISO20171:2005 35 What is to be isolated 5.1 So
41、urce isolation The purpose in this case is the protection of the environment in the vicinity of a vibrating source by modifying the input at the source level. This may include a) isolation of the machine emitting vibrations, b) isolation of the rail track and surrounding subsystems, such as the soil
42、 systems for new and existing railways, and c) isolation of the road embankment and viaducts for highways and removal (suppression) of irregularities. 5.2 Receiver isolation Where source isolation is impossible or impractical (i.e. environmental sources), as for railways or road traffic, or where so
43、urce isolation has proved unsatisfactory, receiver isolation is applied. Sometimes it is an economical compromise. It may include applying isolation to a) a machine operators workstation, b) a new building or elements of the building in the neighbourhood of a railway, tunnel, or heavy traffic roadwa
44、y, c) a sensitive building (concert halls, laboratories, or sensitive installations), d) the support of sensitive equipment (laser tables, computer discs, electronic microscopes, etc.), and e) isolation from environmental sources. 6 Applicability of vibration isolation (when to isolate structures or
45、 mechanical systems) A vibration isolation system may be used additionally to design measures for reducing vibration. It shall not be substituted for such measures, but it may be applied as follows: a) when vibrating machines are designed or installed; b) when constructions, installations or buildin
46、gs containing vibrating machines are designed or modified; c) when vibrating sources are displaced or modified; d) when structure-borne noises occur; e) when designing and constructing buildings, especially sensitive ones in the neighbourhood of railways or high-traffic roads; f) when designing or o
47、rdering sensitive equipment; g) when receiving complaints from people working or living in the area of vibration sources; h) when the limiting values specified in legislation for vibration are exceeded. BSISO20171:20054 7 Measurement and evaluation of vibration conditions In order to choose the corr
48、ect isolation mounting system, it is necessary to make prior measurement and evaluation of vibration in the site. Measurements shall be made under the environmental conditions relevant for the location of the source or receiver. The measurements and analysis should help to provide an understanding o
49、f the origin of the problem and possibly give an indication of the solutions. Measurements shall be made in accordance with an appropriate standard and this standard shall be identified. The measuring position shall be defined in a contract, and the mounting points of transducers and the directions of measurements shall be reported. These measurements shall include time history monitoring over a sufficiently long period to cover the working cycle of
