28、tems; transitions between ballasted and ballastless track systems. NOTE Requirements for characterization of the substructures listed above are included in this standard.

39、y UV Ultra Violet (radiation) ECB Eddy Current Brake 5 External actions 5.1 Railway traffic loading 5.1.1 General The main function of the track is to safely guide the vehicle and to distribute the loads through the ballastless track system to the substructure. The ballastless track system shall car

40、ry the loads from the railway traffic over the design life within the specified operational and safety limits. Loads are generated by: static or quasi static actions; dynamic actions; exceptional actions. Other loads associated with construction, maintenance and emergency access shall be considered

41、as necessary. 5.1 of this standard describes the requirements of railway traffic by vehicles that run on the rails of the ballastless track system. NOTE Other vehicles that run during construction, maintenance or during an emergency or at level crossings on the track surface beside the rails are not

42、 in the scope of this standard. 5.1.2 Vertical loads 5.1.2.1 General If no specific information is available regarding the vertical loading then load model 71 shall be applied as static vertical load for railway traffic to design the rail supporting structure. If specified, the ballastless track sys

43、tem may also be designed for vertical loads which are of short duration or are applied only infrequently during the design life according to the line category. Also models representing real vehicles may be used. 5.1.2.2 Load model 71 The rail traffic covered by load model 71 according to EN 1991-2:2

44、003, 6.3.2, represents all types of vehicles and European standard railway traffic up to 250 kN axle load. 5.1.2.3 Load model according to line category If specified by the customer, vertical load models according to the line categories in EN 15528 shall be applied for the design of the ballastless

45、track system. DIN EN 16432-1:2017-09 EN 16432-1:2017 (E) 9 5.1.2.4 Real vehicle model If specified by the customer, a real vehicle load model representing the conditions of traffic operation for the line (e.g. for specially dedicated rolling stock running on self-contained railways with uniform traf

46、fic and limited variation in vehicle type over the design life) shall be used for the design of the ballastless track system. 5.1.2.5 Additional vertical loads Vertical static loads act unequally on the inner and outer rails due to centrifugal effects in curves or non-uniform load distribution. Such

47、 effects shall be determined on the basis of the applied vehicle model, taking into account of track alignment parameters such as cant and cant deficiency. If track alignment parameters are not specified, the load distribution between inner and outer wheel shall be a maximum of 25 %, equivalent to f

48、actor kq= 1,25 (20 % equivalent to factor kq= 1,20 if tilting vehicles are excluded). NOTE 1 kqis the factor to increase the static wheel loads by additional vertical load (additional quasi static wheel load acting on outside rail along curves). NOTE 2 For more information, see EN 164322:2017, Annex

49、 A. 5.1.2.6 Dynamic vertical loads Dynamic vertical loads are dependent on vehicle speed, the condition of the vehicle and of the track quality, see EN 13848-5 and EN 13848-6. The dynamic vertical load is obtained from multiplication of the static load from the applied load model and the factor, e.g. kd load model 71. Unless otherwise specified a factor of kd= 1,5 shall be applied to all static and quasi-static loads, see 5.1.2.2, 5.1.2.3 and 5.1.2.4. NOTE 2
