PD CEN/TR 17039:2017CEN/TR 17039:2017 (E) 6 1 Scope EN 14363 contains a lot of requirements which were modified during the last revision. The sco

27、pe was also extended. It was found in the working group, that many decisions that were taken to formulate these modifications need to be documented to improve understanding and to allow a later further development if practice of applications shows the necessity. The work for the revision was organis

28、ed in 8 subgroups. Many of these subgroups recorded the way to the proposals in reporting templates, which were used for the editing work. Afterwards discussion was ongoing in WG 10 and in the enquiry process. This available information needs to be summarised and presented in a common format in orde

29、r to allow people not involved in the discussions to understand the background of the modifications. 2 Members of the different drafting groups for the revision of EN 14363 Bold X means group leader Normal X means group member 8.1 Editing 8.2 Test Conditions 8.3 Track Quality, Contact Conditions 8.4

33、est specifications to a description of the process for assessment of running characteristics. In addition, it also contains specifications on an informative basis not necessarily to be used for the acceptance process. The new process also includes the use of simulations. The requirements were furthe

34、r developed starting from the requirements specified in UIC 518:2009 and EN 15827 and refined in discussions inside WG 10 and its relating subgroups and in a second step by the DynoTRAIN research project. The scope was extended to freight vehicles with nominal static vertical wheelset forces up to 2

35、50 kN (previously handled in EN 15687). Also the inclusion of vehicles intended for operation with cant deficiencies above 165 mm (previously handled in EN 15686) was covered by the new requirement to specify the combination of admissible speed and admissible cant deficiency. Additionally the loadin

36、g conditions for the assessment have been defined more precisely. Further a hint to a set of recommended values for admissible cant deficiencies to be chosen for broad international approval was included. It replaces the fixed requirements made for conventional vehicles in the previous version of th

37、e standard. In order to close the open points in the Rolling Stock TSIs about track geometric quality and the achievability of the combination of the specified test conditions during on-track tests, the concept of defined target test conditions and the assessment of achieved test results against tar

38、get test conditions was developed. Further, it needed to be stated that the standard also contains quantities and dependencies that are not directly used for acceptance purposes, but for example for purposes of validation of simulation models or determination of operating conditions outside the refe

39、rence conditions. 3.2 Limitation In order to prevent misuse of the standard for non-railway and non-standard gauge vehicles, it was better described what needs to be considered when using it “by analogy” for such vehicles. PD CEN/TR 17039:2017CEN/TR 17039:2017 (E) 8 To clarify the limits of the scop

40、e, it was stated that the strength of the vehicle and mounted parts, passengers and train crew vibration exposure, comfort, load security and effects of cross wind are out of the scope of this standard as well as the quantification of track deterioration or track fatigue. 3.3 Clarification It was fo

41、und that the old wording needed clarification: “Testing for acceptance of vehicles is based on some reference conditions of track. If these are not respected on certain lines, appropriate measures will be taken (speed modifications, additional tests, etc.).” The discussion in WG 10 showed that it wa

42、s not possible to specify the underlying reference conditions by exact boundaries. The only way for clarification was to: state that all vehicles which were successfully assessed are able to be operated on tracks complying with EN 13803; describe the current state of the art in order to allow the EI

43、M (European Infrastructure Managers) to continue to use their implemented process for operation under demanding track conditions in the future (for example on lines with curve radii below 250 m). This includes two notes explaining why vehicles can also be operated safely outside the target test cond

44、itions. A third note clarifies that the methods of this standard may also be applied to determine operating rules under infrastructure conditions that are more severe than the target test conditions. In this context, it was also stated that the document contains target test conditions for the geomet

45、ric track quality, as they have been adjusted compared to the previous version of the standard. As the target test conditions for stability testing were changed with respect of the target conditions of the TEN (Trans European Network), it was necessary to clarify, that the equivalent conicity to be

46、included in the stability assessment might be higher in some national systems for the time being before the infrastructure target conditions are met. In this context, it was found necessary to state in a note that such national requirements do not necessarily have to include the maximum occurring va

47、lues of equivalent conicity. This makes it possible to find practical test conditions and it reflects also testing at overspeed and that vehicles assessed as stable are in most cases far below the limit values. 3.4 Shifted to other sections The allowances to deviate from the rules laid down if evide

48、nce can be furnished that safety is at least the equivalent to that ensured by complying with these rules and of variations from the defined conditions as specified by the article 7.1 of Directive 91/440 of EC which were stated in the scope of the 2005 version are now described more detailed in a se

49、parate clause (4). It is now stated that in case of deviations, these shall be reported, explained and taken into account when assessing the safety. 4 Fault modes 4.1 What was changed? The explicit requirement on testing with deflated air springs was removed. A new subclause 5.2.2 “Fault modes” and a new subclause in Annex T (Simulation of on-track tests), T.2.5 (Investigation of dynamic behaviour in case of fault modes) was introduced.
