The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possibl

25、or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence bet

30、c, electrical and electronic equipment/components (hereafter only referred to as equipment) to be fitted on to railway vehicles. Random vibration is the only method to be used for equipment/component approval. The tests contained within this standard are specifically aimed at demonstrating the abili
31、ty of the equipment under test to withstand the type of environmental vibration conditions normally expected for railway vehicles. In order to achieve the best representation possible, the values quoted in this standard have been derived from actual service measurements submitted by various bodies f
32、rom around the world. This standard is not intended to cover self-induced vibrations as these will be specific to particular applications. Engineering judgement and experience is required in the execution and interpretation of this standard. This standard is suitable for design and validation purpos
33、es; however, it does not exclude the use of other development tools (such as sine sweep), which may be used to ensure a predetermined degree of mechanical and operational confidence. To assist product design for compliance with this standard, guidance is given in annex B which allows comparison with
34、 alternative design methods. The test levels to be applied to the item under test are dictated only by its location on the train (i.e. axle, bogie or body-mounted). It should be noted that these tests may be performed on prototypes in order to gain design information about the product performance un
35、der random vibration. However, for attestation of testing purposes the tests have to be carried out on equipment taken from normal production.

36、IEC) 2002-08-08 6 RAILWAY APPLICATIONS ROLLING STOCK EQUIPMENT SHOCK AND VIBRATION TESTS Scope This International Standard specifies the requirements for testing items of equipment intended for use on railway vehicles which are subsequently subjected to vibrations and shock owing to the nature of ra
37、ilway operational environment. To gain assurance that the quality of the item is acceptable, it has to withstand tests of reasonable duration that simulate the service conditions seen throughout its expected life. Simulated long-life testing can be achieved in a number of ways each having their asso
38、ciated advantages and disadvantages, the following being the most common: a) amplification: where the amplitudes are increased and the time base decreased; b) time compression: where the amplitude history is retained and the time base is decreased; c) decimation: where time slices of the historical
39、data are removed when the amplitudes are below a specified threshold value. The amplification method as stated in a) above, is used in this standard and together with the publications referred to in clause 2; it defines the default test procedure to be followed when vibration testing items for use o
40、n railway vehicles. However, other standards do exist and may be used with prior agreement between the manufacturer and the customer. In such cases attestation of testing against this standard will not apply. Where service information is available comparison with the standard can be performed using
41、the method outlined in annex A. Whilst this standard is primarily concerned with railway vehicles on fixed rail systems, its wider use is not precluded. For systems operating on pneumatic tyres, or other transportation systems such as trolleybuses, where the level of shock and vibration clearly diff
42、er from those obtained on fixed rail systems, the supplier and customer can agree at the tender stage, the test levels. It is recommended that the frequency spectra and the shock duration/amplitude be determined using the guidelines set out in annex A. Items tested at levels outside those quoted in
43、this standard can not be certified against the requirements of this standard. An example of this is trolleybuses, whereby body-mounted trolleybus equipment could be tested in accordance with category 1 equipment referred to in the standard. This standard applies to single axis testing. Multi-axis te
44、sting is outside the scope of this standard. The test values quoted in this standard have been divided into three categories dependent only upon the equipments location within the vehicle. Category 1 Body mounted Class A Cubicles, subassemblies, equipment and components mounted directly on or under
45、the car body. Class B Anything mounted inside an equipment case which is in turn mounted directly on or under the car body. NOTE Class B should be used when it is not clear where the equipment is to be located. Licensed Copy: London South Bank University, London South Bank University, Sat Dec 30 06:

Category 3Axle mounted Subassemblies, equipment and components or assemblies whic
47、h are to be mounted on the wheelset assembly of a railway vehicle. NOTE In the case of equipment mounted on vehicles with one level of suspension such as wagons and trucks, unless otherwise agreed at the tender stage, axle mounted equipment will be tested as category 3, and all other equipment will
48、be tested as category 2. The cost of testing is influenced by the weight, shape and complexity of the item under test. Consequently at the tender stage the supplier may propose a more cost effective method of demonstrating compliance with the requirements of this standard. Where alternative methods
49、are agreed it will be the responsibility of the supplier to demonstrate to his customer or his representative that the objective of this standard has been met. If an alternative method of evaluation is agreed, then the item tested cannot be certified against the requirement of this standard. This standard is intended to evaluate equipment which is attached to the main structure of the vehicle (and/or components mounted thereon). It is not intended to test
