30、ic 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 within this standard are specifically aimed at demonstrating the ability of the equipment unde
31、r 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 from around the world. Th
32、is 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 purposes; however, it does not
33、 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 under test are dictated only by its location on the train (i.e. axle, bogie or body-mounted).
34、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 have to be carried out on equipment taken from normal production. BS EN 61373:2010 61373 IEC
35、:2010 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 vehicles which are subsequently subjected to vibrations and shock owing to the nature of railway op
36、erational 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 life. Simulated long-life testing can be achieved in a number of ways each having their associa
37、ted 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 (increase of the frequency); c) decimation: where time
38、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 publications referred to in Clause 2; it defines the default test procedure to be followed when vibratio
39、n 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 standard will not apply. Where service information is available tests can be performed using the m
40、ethod 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 than or equal to those specified in the test report). Whilst this standard is primarily conce
41、rned 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 differ from those obtained on fixed rail systems, the supplier and customer
42、 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 lower than those quoted in this standard cannot be fully certified against the requirements of th
43、is 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. However multi-axis testing may be used with prior agreement between the manufa
44、cturer 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 Cubicles, subassemblies, equipment and components mounted directly on or under the car body. BS EN
45、61373:2010 8 61373 IEC:2010 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 equipment is to be located. Category 2 Bogie mounted Cubicles, subassemblies, equipment and component
46、s 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 vehicle. NOTE 2 In the case of equipment mounted on vehicles with one level of suspension such as w
47、agons 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 stag
48、e the supplier may propose a more cost-effective method of demonstrating compliance with the requirements of this standard. Where alternative methods 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 equipment tested cannot be certified against the requirement of this standard. This standard is intended to evaluate equipment which is attached to the main struct
