The motions of the vehicle body transmit their effects to
29、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 through the interfaces.

34、rve 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 characteristics and vehicle body
35、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-static) to 2 Hz for Com

BS EN 12299:2009 EN 12299:2009 (E) 14 This
37、 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 (change of mean lateral acce
38、leration 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 Transitions and in Comfort on D
39、iscrete 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 based on the assessment of t
40、he 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 taken into account in thi

42、fication of comfort 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
43、 and Annex H. This 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.
