29、 exposure measured on the floor of the vehicle body for the purpose of vehicle assessment with respect to ride comfort. 5.2 Passenger exposure to vibrations Railway transport exposes passengers to vibrations related to the dynamic motions of the vehicle body. The motions of the vehicle body transmit
30、 their effects to the human body through the following interfaces: a) in the standing position: 1) floor feet b) in the seated position: 1) headrest neck 2) arm rest arms 3) seat hip 4) backrest back 5) floor feet The type of transmission is whole-body transmission which acts on the whole body throu

34、by asking test subjects) combined measurements 5.4 Characteristics of railway vehicle motions The basic typical motion characteristics, referred to the type of measurement and evaluation, are: a) Different properties, depending on the type of evaluation: 1) quasi-stationary (Mean Comfort) 2) non-sta
35、tionary (Comfort on Curve Transitions and Comfort on Discrete Events). b) The frequency range of motions expected in rail vehicles includes, in the lateral direction: 1) up to 15 Hz: due to track characteristics, vehicle body swing-roll and yaw modes at lower frequencies, and suspensions characteris
36、tics and vehicle body modes at higher frequencies; c) The frequency range of motions expected in rail vehicles includes, in the vertical direction: 1) up to 40 Hz: due to track characteristics, suspensions characteristics, wheel defects, vehicle body modes; d) Range of frequencies from 0 Hz (quasi-s
37、tatic) to 2 Hz for Comfort on Curve Transitions and for Discrete Events. 5.5 Ride comfort The ride comfort for passengers is the complex sensation, produced on the passenger by the vehicle body motions of the railway vehicle, transmitted to the whole body through the interfaces. DIN EN 12299:2009-08
38、 EN 12299:2009 (E) 14 This sensation is classified as: a) average sensation, based on the vibration applied on a long-time basis (several minutes); b) quasi-static lateral acceleration due to curving. c) instantaneous sensation: a sudden change of the average sensation, due to a short-basis event (c
39、hange of mean lateral acceleration level with possible oscillation, roll motion at significant velocity and lateral jerk); The first type of sensation is taken into account in the Mean Comfort evaluation. The second and the third type of sensation are taken into account in the Comfort on Curve Trans
40、itions and in Comfort on Discrete Events. 5.6 Direct and indirect measurements The quantification of ride comfort for passengers is performed through indirect measurements, i.e. measuring and post-processing the relevant motion quantities. Other types of tests and evaluation, such as direct tests ba
41、sed on the assessment of the perceptions of tested passengers, and combined tests, including both direct and indirect tests, are not defined in this standard. However, some guidance for direct tests is given in Annex F. 5.7 Summary table of procedures The evaluation of ride comfort for passengers is
42、 taken into account in this standard by: a) procedure for the quantification of comfort index “Mean Comfort” by the Standard Method (MVN ), see Clause 6 and Annex H; b) procedure for the quantification of comfort index “Mean Comfort” by the Complete Method (VAN ,VDN ), see Clause 6 and Annex H; c) p
43、rocedure for the quantification of comfort index “Comfort on Curve Transitions” (CTP ), see Clause 7 and Annex H; d) procedure for the quantification of comfort index “Comfort on Discrete Events” (DEP ), see Clause 8 and Annex H; e) procedure for the quantification of Continuous Comfort (CxC ,CyC ,C
44、zC ), see Clause 6 and Annex H. This standard also provides requirements for assessment of vehicles with respect to ride comfort by Continuous Comfort and the Standard Method (MVN ) with acceptable deviations; see Annex E.
