Railway applications - Ride comfort for passengers - Measurement and evaluation

This standard specifies methods for quantifying the effects of vehicle body motions on ride comfort for passengers and vehicle assessment with respect to ride comfort. The effect considered is:
   discomfort, associated with relatively low levels of acceleration and roll velocity.
Other effects, not included in the standard, are associated with higher acceleration levels:
   health risk effect: physical damage and psychological deterioration.
The standard applies to passengers travelling in railway vehicles on railway lines, including main, secondary and suburban lines. This standard could be used as a guide for other railway vehicles, for example locomotives, metros, trams, etc.
The standard applies to passengers in good health.
This standard applies to measurements of motions. It also applies to simulated motions.

Bahnanwendungen - Fahrkomfort für Fahrgäste - Messung und Auswertung

Diese Europäische Norm legt Methoden zur Bewertung der Auswirkungen von Bewegungen des Fahrzeugs auf den Fahrkomfort der Fahrgäste und für die Fahrzeugbewertung fest.

This standard defines as the Standard Method:
a) The Standard Method for Mean Comfort evaluation, taking into account the effects of vibration exposure measured on the floor of the vehicle body. This standard also defines several methods for special applications: b) taking into account the short time effects of vibration exposure measured on the floor of the vehicle body as Continuous Comfort for the longitudinal, lateral, and vertical direction; 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 (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 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 The 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: SIST EN 12299:2009

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-stationary (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 characteristics 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-static) 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.
