3、ents National foreword This D r a f t for Development is the English language version of ENV 12299: 1939. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because the subject matter is
4、still under technical development requiring wider exposure. It should be applied on t h i s provisional basis, so that information and experience of its practical application may be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience can be repor
5、ted to the European organization responsible for its conversion into a European Standard. A review of this publication will be initiated 2 years after i t s publication by the European organization so that a decision can be taken on its status at the end of its threeyear life. The commencement of th
6、e review period will be notified by an announcement in Update S h m , - taking into account, (as recommendation), the vibration exposure measured on the interfaces (the complete method for Mean Comfort evaluation); - taking into account, (as recommendation), the effects on Ride comfort for passenger
7、s of: - discrete evenis (Comfort on Discrete Events); - running on curve transitions (Comfort on Curve Transitions). The standard is published as European Prestandard (ENV), due to - the lack of experience in the applicatbn of the Mean Comfort measurement and evaluation criteria, based on UIC-leaet
8、513, up to now experimentally approved in UIC, both for the normative part (N,J and for the informative pari (N,. NJ; - the lack of experience in the application of the recommended P , , P , Comfort indexes, up to now based on the technical experience in studies and direct tests given mainly in Grea
9、t Britain and in indirect tests performed by Italy, Germany and Switzerland. Railway transport exposes passengers to vibrations related io the dynamic movements of the carbody. The movements of the carbody transmit their effects to the human body through the foliowing intedaces: - in the standing po
10、sition: - floor-feet - in the seated position: - headrest - neck - arm rest - upper arms - seat - hip - seat-back - floor-feet The type of transmission is whole-body transmission (see 3.4), which acts on the whole body through the interfaces (see 3.3 ). The effect produced by the carbody movements c
11、onsidered in this ENV is: - discomfort (eect on comfort, see 3 . 2 ) , associated with relatively low levels of acceleration, Other effects, not included in the standard, are associated with higher acceleration levels: - health risk effect: physical damage and psychological deterioration.

17、447 Page 6 ENV 12299: 1999 c) Characteristics of rallway vehicle movemenh The basic typical characteristics, referred to the type of measurement and evaluation, are: - range of frequencies from O to 2 Hz for Comfort on Curve Transitions and for Discrete Events, from 0,4 to 80 Hz for Mean Comfort eva
18、luation. For the latter, Witti a large pari in the subrange: - 0,4 up to 3 . 0 Hz in the lateral direction, - 0,4 up to 20 Hz in the vertical direction; - relatively low level of amplitude; - different properties, depending on the type of evaluation: stationary (Mean Comfort). non-stationary (Discre
19、te Events), quasi-static (mean lateral acceleration on Discrete Events), dynamic with relevant transient components (peak-to-peak on Discrete Events, Comfort on Transitions), highly non-linear (on Curves, on Discrete Events), linear (Mean Comfort). d) Ride comfort for passengers The Ride Comfort for
20、 passengers is the complex sensation, produced on the passenger by the carbody movements of the raiiway vehkie, transmitted to the whde body through the interfaces. This sensation is classified as: - average sensation, based on the vibration applied on a iong-time basis (at least some minutes), - in
21、stantaneous sensation: a sudden modification of the average sensation, due to a short-basis event (change of mean lateral acceleration value, roll movement at significant speed, lateral jerk w i t h possible oscillation). Both the first and the second type of sensation are taken into account in the
22、Mean Comfort evaluation. The second type of sensation is taken into account in the Comfort on Cunre Transitions and in Comfort on Discrete Events. e) D I M and Indirect measurements The quantification of Ride comfort for passengers i s performed through indirect measurements, .e. measuring and post-
23、processing the relevant parameters (see 3.5). Other types of tests and evaluation, such as direct tests based on the direct assessment of the perceptions of tested passengers, and combined tests, including both direct and indirect tests, are not quantified in this European Prestandard.
