They are not exclusive and more may be added as information becomes available. 6 Responsibilities The customer sha
19、ll provide the supplier with a detailed description of the requirements of the bogie design in the form of a technical specification incorporating all appropriate mandatory regulations. The customer shall also define the parts of the acceptance procedure (clause 9) and the quality requirements (clau
20、se 10), which he specifically requires. The customer shall specify the way in which the supplier is to provide evidence to show that the requirements have been met. NOTE If the customer is unable to define the specification completely the supplier may propose a specification and submit it to the cus
21、tomer for approval. It is the suppliers responsibility to design the bogie frame in accordance with the specification. 7 Contents of technical specification 7.1 Scope The technical specification shall consist of all the information describing the functional requirements of the bogie frame and the in
22、terfaces with associated components and assemblies. It shall also comprise, as a minimum, the general requirements of use, the conditions associated with the vehicle equipped with the bogies, the operating characteristics, the conditions associated with maintenance and any other particular requireme
23、nts of the customer. 7.2 General requirements The customer shall indicate the type of bogie required in terms of its use in accordance with the categories in clause 5. The customer shall also indicate in the technical specification the intended life of the bogie, its average annual distance run and
24、its total distance run. 7.3 Vehicle conditions and interfaces The specification shall include, but not be limited to, information on: EN 13749:2005 (E) 12 vehicle masses; vehicle geometry (e.g. available space, position of the centre of gravity); bodybogie connections (e.g. mechanical, pneumatic, el
25、ectric); braking equipment; motors and transmission; tilt systems (where applicable). 7.4 Operational characteristics The specification shall include, but not be limited to, information on the characteristics to which the bogie is to be designed: loading conditions (e.g. changes in payload and frequ
26、ency, dynamic load spectra); method of loading (e.g. progressive or sudden); maximum axle loads; maximum operating speed; speeds on curves and cant deficiency; starts and stops (i.e. number and frequency, acceleration rates, deceleration rates, including effect of wheel slip/slide control); exceptio
27、nal conditions (e.g. derailments, lifting, allowable instability). 7.5 Line characteristics The specification shall include information on all the characteristics of the railway network for which the bogie is to be designed that have an influence on the loads applied to the bogie, including the foll
28、owing: profiles of the tracks, including service depot tracks, (e.g. radius of curves, number of curves, percentage of distance covered on straight lines and on curves, maximum and normal levels of twist, percentage of use on service depot tracks, number of junctions, cant); types of track (e.g. cla
29、ssification of quality including construction, roughness and irregularities); loading gauge. 7.6 Environmental conditions The specification shall include information on the characteristics of the environment that can have an influence on the behaviour of the bogie frame and that the bogie frame shal
30、l be designed to withstand, including: climatic conditions (e.g. temperature, humidity, rain, snow, floods, wind); aggressive agents (e.g. corrosion, erosion, dirt). EN 13749:2005 (E) 13 7.7 Maintenance and inspection All the conditions of maintenance planned for the bogie and which can have an infl
31、uence on the design and behaviour of a bogie frame shall be indicated in the technical specification, including the following: description of maintenance operations, including their frequency; the use of machines for washing the bogie (cleaning agents); handling requirements (e.g. lifting, towing);
32、wear limits for different components. 7.8 Particular requirements The customer shall indicate in the technical specification any particular requirements that are not covered by the above clauses, for example, materials, types of construction and methods of assembly (e.g. treatment of welds, shot pee
33、ning). 8 Verification of the design The customer shall require the supplier to use all necessary means (e.g. calculations, drawings, tests) to carry out the design. The design of the bogie frame shall be verified by the documents defined by the customer in the contract (e.g. calculations, drawings,
34、test reports) which allow: the customer to carry out all the checks which he considers necessary; the supplier to design and manufacture the bogie frames in accordance with the requirements of the quality plan (see clause 10). 9 Acceptance of the design 9.1 General The aim of the acceptance programm
35、e is to prove that the design of the bogie frame fulfils the conditions defined in the technical specification. In addition, it shall show that the behaviour of the bogie frame, constructed according to the design, will give satisfactory service without the occurrence of defects such as catastrophic
36、 rupture, permanent deformation and fatigue cracks. It shall further demonstrate that there is no adverse influence on the associated bogie components or sub- assemblies. EN 13749:2005 (E) 14 The specification shall include details of how the bogie design is to be accepted and shall state all the pa
37、rameters that are necessary for the application of the different parts of the procedure. These parameters shall be defined in three stages: the acceptance procedure (e.g. combination of load cases for calculations and static tests, programmes for fatigue tests, routes for on-track tests); the values
38、 of the different load cases; the acceptance criteria (treatment of measured or calculated values, limiting stresses, criteria for completion of fatigue tests). Clause 9.2 defines which parts of the acceptance procedure should be included in any particular case. NOTE In order that the acceptance pro
39、cedure is completely defined, the supplier should identify the methods of demonstrating conformance to the requirements if the customer has not incorporated them into the specification. 9.2 The acceptance programme 9.2.1 Content The procedure for the acceptance of the mechanical strength of a bogie
40、frame shall be established on the basis of: calculations; static tests; fatigue tests; on-track tests. The content of the procedure shall depend on the importance of the problem to be dealt with and also take account of economic factors. For a new design of bogie frame destined for a new type of app
41、lication all four validation stages shall be used though, with the agreement of the customer, the fatigue tests can be replaced by other methods of demonstrating the required fatigue life. In the case of an existing design of bogie frame intended for a new application, or a modification to an existi
42、ng design, a reduced programme can be used, depending on the significance of the differences. If the differences are small, calculations supported by measurements made during a limited test programme will be sufficient to validate the design. Static tests and fatigue tests shall be carried out in ac
43、cordance with the customer specification and to a level that the supplier considers necessary to validate the design to his own satisfaction. In the case of an order for a very small number of bogies it might be impractical, for economic reasons, to justify all four stages of the acceptance procedur
44、e. In such cases calculations shall always be carried out and these shall be complemented by at least one type of test. In cases where all four stages of the acceptance procedure are not to be applied this can lead to a reduced confidence in the validity of the design. To compensate for a reduced ac
45、ceptance procedure, greater safety factors shall be adopted in the design and test acceptance parameters, consistent with the degree of originality in the design or its application. EN 13749:2005 (E) 15 9.2.2 Calculations The calculations shall include the following information: design load cases (a
46、s indicated in annexes A, B, C, and D); combinations of load cases; compatibility of the axlebox with the requirements of the bearings (e.g. permissible deformations); methods of calculation; methods of evaluation, interpretation and combination of calculated stresses; limiting stresses (i.e. static
47、, fatigue); any other acceptance criteria. Annex E gives guidance on factors to be considered in defining a calculation programme. 9.2.3 Static tests The static acceptance test programme shall include the following: magnitudes and positions of forces to be applied; combinations of forces to be appli
48、ed; positions and types of measurements to be made (e.g. displacements, strains, types of transducer); methods of evaluation and interpretation of measured stresses; limiting stresses; any other acceptance criteria. Annex F indicates general considerations and gives examples of programmes for static
49、 tests. The tested bogie frame shall be of the same type and manufacture as the bogie frames to be used in service (i.e. it shall have no differences in any critical factors that could influence the outcome). The test rig equipment shall be capable of producing, as far as is reasonably practicable, the same stresses as those which would appear on the bogie frame when placed under its intended vehicle and su
