14、 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 body interested in a subject for which a technical committe

15、e 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 Electrotechnical Commission (IEC) on all matters of electrotechni

16、cal 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 by the technical committees are circulated to the member b

ISO 14837-1 was prepared by Technical Committee ISO/TC 108, Mechanical vibration and shock, Subcommittee SC 2, Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures. ISO 14837 consists of the following parts, under

20、Many if not all ground transportation systems can give rise to ground-borne vibration and/or ground-borne noise. Railways are by far the most common and significant source as a consequence of running steel wheels over steel rail. Rail systems of all types generate ground-borne vibration and/or groun

21、d-borne noise, which (especially in urban settings) can have an undesirable environmental impact. An assessment of the likely ground vibration and response of structures at different distances from the source may be required. This requirement may arise for planning purposes where a) a new or extende

22、d railway or new or altered buildings are proposed, b) changes in dynamic characteristics of track or dynamic characteristics of trains are proposed, c) a change in train operations is proposed (e.g. change of total length, speed, service pattern), or d) assistance is needed in the evaluation of vib

23、ration mitigation measures. Appropriate prediction of ground-borne vibration and/or ground-borne noise is the first of the two essential blocks required to assess vibration effects of new or modified rail systems on existing buildings, or the effects on new buildings next to or over existing rail sy

24、stems. Ground-borne vibration and/or ground-borne noise criteria (and/or limit values) in the receiving building are the second block of any assessment. Criteria and limit values, however, are covered by national standards and other International Standards. Prediction of ground-borne vibration and/o

25、r ground-borne noise from rail systems is a complex and developing technical field. This part of ISO 14837 provides guidelines on the essential considerations associated with developing prediction models to ensure that they are “fit for purpose” and that they are consistent in their approach. Guidan

26、ce is given on calibrating and validating a model and verifying its implementation, which are vital steps in quantifying and improving the models accuracy. Table 1 shows in outline the stages to be observed for new or modified rail systems or building developments alongside rail systems. This part o

27、f ISO 14837 provides general introduction and guidance. Detailed matters will be covered in future parts, the titles of which are given in the Foreword.

32、: General guidance 1 Scope This part of ISO 14837 provides general guidance on ground-borne vibration generated by the operation of rail systems, and the resultant ground-borne noise in buildings. It lists the factors and parameters that need to be taken into consideration and offers guidance on pre

33、diction methods appropriate for a range of circumstances (e.g. to support the assessment of effects on human occupants and sensitive equipment or operations inside the buildings in addition to the predictions required to assess the risk of damage to building structures). Attention is paid in this pa

34、rt of ISO 14837 to characteristics of the source: emission (e.g. train, wheel, rail, track, supporting infrastructure), propagation path: transmission (e.g. ground condition, distance), and receiving structures: immission: (e.g. foundations, form of building construction). The guidance covers all fo

35、rms of wheel and rail systems, from light-rail to high-speed trains and freight. This part of ISO 14837 provides guidance for rail systems at-grade, on elevated structures and in tunnels. This part of ISO 14837 does not deal with vibration arising from the construction and maintenance of the rail sy

36、stem. It does not deal with airborne noise. Structure-radiated noise from elevated structures, which can have a significant environmental impact, is also excluded. 2 Normative references The following referenced documents are indispensable for the application of this document.

43、ithout a change to the system NOTE 1 A reduction in the metric value is shown with a negative sign when the insertion gain is expressed in decibels. NOTE 2 Although “insertion gain” is the preferred term, the term “insertion loss” is also used. A reduction in the metric value is shown with a positiv

44、e sign when the insertion loss is expressed in decibels. 3.11 unsprung mass collective mass of elements such as wheels, axles and, where appropriate, brake discs, axle hung motor, gearboxes, that bear on the rail below the vehicle suspension BS ISO 14837-1:20053 4 Overview of ground-borne vibration

45、and ground-borne noise 4.1 Circumstances of interest Ground-borne vibration and/or ground-borne noise can give rise to effects on human occupants of buildings. Very sensitive equipment or its operation can also be adversely affected. In extreme cases, ground-borne vibration can be such that there is

46、 a risk of damage to buildings and other structures. This part of ISO 14837 provides guidance on the prediction models required to assess the effects of vibration on human beings (but not animals) and very sensitive equipment inside buildings, and on the buildings themselves. People will perceive vi

47、bration in different forms, depending on the frequency range, as mechanical vibration of the human body (relevant frequency range 1 Hz to 80 Hz) and/or as sound, ground-borne noise emitted by vibrating parts of a building; i.e. the walls, floor and ceiling (relevant frequency range 16 Hz to 250 Hz).

48、 NOTE 1 Vibration is perceived in different forms, either as whole body vibration (1 Hz to 80 Hz), or perceived through the tactile sense, which may have a higher frequency range. NOTE 2 In unusual circumstances, frequencies as low as 16 Hz or as high as 500 Hz may be relevant to ground-borne noise.

49、 NOTE 3 Secondary effects include higher frequency noise emitted by rattling of some items such as glasses, dishes, windowpanes, ceilings, light fittings and some furniture. Guidance is not provided on the prediction of sound generation by this mechanism because it is difficult to quantify, although it can be a significant source of disturbance. Vibration in buildings can affect technical equipment; i.e. sensitive measuring instruments or manufacturin
