32、irements for random vibration and shock testing items of pneumatic, electrical and electronic equipment/components (hereinafter 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 wit
33、hin this standard are specifically aimed at demonstrating the ability 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 der
34、ived from actual service measurements submitted by various bodies from 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 s
35、tandard. This standard is suitable for design and validation purposes; 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. The test levels to be applied to the equipment und
36、er 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 under random vibration. However, for test certification purposes the tests h
37、ave to be carried out on equipment taken from normal production. BS EN 61373:2010EN 61373:2010 (E) 7 RAILWAY APPLICATIONS ROLLING STOCK EQUIPMENT SHOCK AND VIBRATION TESTS 1 Scope This International Standard specifies the requirements for testing items of equipment intended for use on railway vehicl
38、es which are subsequently subjected to vibrations and shock owing to the nature of railway operational environment. To gain assurance that the quality of the equipment is acceptable, it has to withstand tests of reasonable duration that simulate the service conditions seen throughout its expected li
39、fe. Simulated long-life testing can be achieved in a number of ways each having their associated 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 re
40、tained and the time base is decreased (increase of the frequency); c) decimation: where time slices of the historical 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 publication
41、s referred to in Clause 2; it defines the default test procedure to be followed when vibration testing items for use on railway vehicles. However, other standards exist and may be used with prior agreement between the manufacturer and the customer. In such cases test certification against this stand
42、ard will not apply. Where service information is available tests can be performed using the method outlined in Annex A. If the levels are lower than those quoted in this standard, equipment is partially certified against this standard (only for service conditions giving functional test values lower
43、than or equal to those specified in the test report). 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
44、vibration clearly differ from those obtained on fixed rail systems, the supplier and customer can agree on the test levels at the tender stage. It is recommended that the frequency spectra and the shock duration/amplitude be determined using the guidelines in Annex A. Equipment tested at levels lowe
45、r than those quoted in this standard cannot be fully 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
46、 axis testing. However multi-axis testing may be used with prior agreement between the manufacturer and the customer. 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 Cubicl
47、es, subassemblies, equipment and components mounted directly on or under the car body. BS EN 61373:2010EN 61373:2010 (E) 8 Class B Anything mounted inside an equipment case which is in turn mounted directly on or under the car body. NOTE 1 Class B should be used when it is not clear where the equipm
48、ent is to be located. Category 2 Bogie mounted Cubicles, subassemblies, equipment and components which are to be mounted on the bogie of a railway vehicle. Category 3 Axle mounted Subassemblies, equipment and components or assemblies which are to be mounted on the wheelset assembly of a railway vehi
49、cle. NOTE 2 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 be tested as category 2. The cost of testing is influenced by the weight, shape and complexity of the equipment under test. Consequently at the tender stage the supplier may propose a more cost-effective method of demo
