14、ional 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 committee has been established has the right to be represented on that committee. Interna
15、tional 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 electrotechnical standardization. International Standards are drafted in accordance with the r
16、ules 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 bodies for voting. Publication as an International Standard requires approval by a
17、t 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 rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2017-2 was prepared by Technical Committee ISO/
18、TC 108, Mechanical vibration, shock and condition monitoring. The first edition, together with ISO 2017-1:2005 cancels and replaces ISO 2017:1982 which has been technically revised.

21、vices. Some suppliers of shock and vibration isolators (resilient mounts) have experience covering a wide variety of applications. In most instances, they are willing to use their background information for solving the users isolation problems. However, it is frequently difficult for the supplier to
22、 provide this service, because the customer, the user or the producer of vibration source or receiver has not furnished sufficient information regarding the application. On the other hand, the user is sometimes handicapped in applying isolators properly because sufficient technical information is no
23、t furnished by the supplier. Consequently, the user will often conduct his own experimental evaluation of the isolator and may unknowingly duplicate work already carried out by the supplier. In some cases of vibration source or receiver, the producer provides the isolating system. To do that he need
24、s detailed information from the customer relating to his future application, site and environment. This part of ISO 2017 is intended to serve as guide for the exchange of technical information regarding the application of isolation elements for vibrations and shocks generated by railway systems, bet
25、ween the customer, supplier of resilient devices and producer of vibration source or receiver as required for their proper application. For the purposes of this part of ISO 2017, a resilient device is defined as a flexible element or system used between an equipment item and its supporting structure
26、 to attenuate the transmission of shock or vibration from the railway systems to the structure.

29、hes requirements to ensure appropriate exchange of information regarding the application of isolation for vibrations and shocks generated by railway systems. This part of ISO 2017 is applicable to the construction of new railway systems. It may also be applied to previously installed systems when th
30、e user wishes to solve a new vibration problem arising from railroad degradation, when new environmental land use planning requirements are put in place, or when new vibration-sensitive land development occurs in proximity to existing railway systems. It applies to vibration problems encountered in
31、a railway environment but does not address vibration problems within railway cars (carriages) themselves. This part of ISO 2017 intends to give appropriate responses to questions highlighted by the producer and users (why, what, when and how to isolate mechanical systems). 2 Normative references The

If the support stiffness did not vary along the track, a static load would then come on during the train passage.
45、 At train speeds below wave propagation speeds in the track and soil, this would present essentially a standing load problem to be solved. However, in practice the rail is supported at intervals via rail track fasteners traditionally fixed to sleepers laid within ballast. The rail therefore provides
46、 varying support stiffness to the moving load. The static load therefore appears and disappears at these discrete supports, the periodicity of which is a function of train speed, spacing between axles, and the spacing between the discrete supports. This loading is therefore often referred to as quas
47、i-static, or parametric, as it is due to a change in parameter, such as stiffness. Measurements of wayside vibration indicate peaks in the frequency spectrum that tie in with the sleeper passage and axle passage frequencies. The ground vibration that results from these discrete supports tends to cau
48、se peaks in the frequency spectrum below 80 Hz (train speed dependant), and is partly responsible for vibration that is felt at the wayside. Another mechanism relates to wheel and rail roughness, arising either from manufacturing tolerances or from in-service wear. On the wheel there are wheel flats that develop due to braking. The rail surface may exhibit corrugation. As the wheel traverses this irregular profile, the unsprung mass (wheel set) is accel
