28、of the terms, max 1s y c) taking into account the vibration exposure measured on the seat or other interfaces on ride comfort as the Complete Method for Mean Comfort evaluation; d) taking into account the effects of: 1) discrete events (Comfort on Discrete Events) and 2) running on curve transitions
29、 (Comfort on Curve Transitions) on ride comfort. e) taking into account the vibration 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
30、 to the dynamic motions of the vehicle body. The motions of the vehicle body transmit 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 T
31、he type of transmission is whole-body transmission which acts on the whole body through the interfaces. 5.3 Application Table 2 lists the items included or excluded from this standard: Licensed CopyChinese University of Hong Kong, 13/06/2009 04:57, Uncontrolled Copy, (c) BSI BS EN 12299:2009 EN 1229

34、ecific actions (reading, writing etc.) Type of measurement indirect measurement, i.e. measurement of motion environment by different motion quantities direct measurements (by asking test subjects) combined measurements 5.4 Characteristics of railway vehicle motions The basic typical motion character
35、istics, 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-stationary (Comfort on Curve Transitions and Comfort on Discrete Events). b) The frequency range of motions expected in rail vehicl
36、es 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 characteristics and vehicle body modes at higher frequencies; c) The frequency range of motions expected in rail vehicles includes, in the
37、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-static) to 2 Hz for Comfort on Curve Transitions and for Discrete Events. 5.5 Ride comfort The ride comfort for passengers is the
38、 complex sensation, produced on the passenger by the vehicle body motions of the railway vehicle, transmitted to the whole body through the interfaces. Licensed CopyChinese University of Hong Kong, 13/06/2009 04:57, Uncontrolled Copy, (c) BSI BS EN 12299:2009 EN 12299:2009 (E) 14 This sensation is c
39、lassified 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 (change of mean lateral acceleration level
40、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 Transitions and in Comfort on Discrete Events.
41、 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 based on the assessment of the perceptions
42、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 taken into account in this standard by:
43、a) procedure for the quantification of comfort index “Mean Comfort” by the Standard Method ( MV N), see Clause 6 and Annex H; b) procedure for the quantification of comfort index “Mean Comfort” by the Complete Method ( VA N, VD N), see Clause 6 and Annex H; c) procedure for the quantification of com
44、fort index “Comfort on Curve Transitions” ( CT P), see Clause 7 and Annex H; d) procedure for the quantification of comfort index “Comfort on Discrete Events” ( DE P), see Clause 8 and Annex H; e) procedure for the quantification of Continuous Comfort ( Cx C, Cy C, Cz C), see Clause 6 and Annex H. T
45、his standard also provides requirements for assessment of vehicles with respect to ride comfort by Continuous Comfort and the Standard Method ( MV N) with acceptable deviations; see Annex E. Motion quantities and position of measurement for the different comfort indices are listed in Table 3. Table
