SIST EN 13103:2009/kFprA1:2010

Railway applications - Wheelsets and bogies - Non-powered axles - Design method

This standard:
1) defines the forces and moments to be taken into account with reference to masses and braking
conditions;
2) gives the stress calculation method for axles with outside axle journals;
3) specifies the maximum permissible stresses to be assumed in calculations for steel grade EA1N defined
in EN 13261;
4) describes the method for determination of the maximum permissible stresses for other steel grades;
5) determines the diameters for the various sections of the axle and recommends the preferred shapes and
transitions to ensure adequate service performance.
This standard is applicable to:
6) solid and hollow axles of railway rolling stock used for the transportation of passengers and freight;
7) axles defined in EN 13261;
8) all gauges3.
This standard is applicable to axles fitted to rolling stock intended to run under normal European conditions.
Before using this standard, if there is any doubt as to whether the railway operating conditions are normal, it is
necessary to determine whether an additional design factor has to be applied to the maximum permissible
stresses. The calculation of wheelsets for special applications (e.g. tamping/lining/levelling machines) may be
made according to this standard only for the load cases of free-running and running in train formation. This
standard does not apply to workload cases. They are calculated separately.
For light rail and tramway applications, other standards or documents agreed between the customer and
supplier may be applied.
Non-powered axles of motor bogies and locomotives are analysed according to the requirements of
EN 13104.

Overview

SIST EN 13103:2009/kFprA1:2010 is a European standard developed by CEN that provides the design method for non-powered axles used in railway applications. It specifically addresses the wheelsets and bogies of railway rolling stock that operate under normal European conditions. This standard guides the design process by defining forces and moments, setting stress calculation methods, and specifying limits for various axle components, with a focus on ensuring safety, durability, and interoperability in accordance with EU Directive 2008/57/EC.

Key Topics

• Forces and Moments: The standard defines the forces and moments to consider in design based on axle masses and braking conditions, ensuring accurate load assessments.
• Stress Calculation Method: It provides a comprehensive method to calculate stresses on axles with outside axle journals, a critical factor for safe axle design.
• Permissible Stress Limits: Specifies maximum allowable stresses for steel grade EA1N as per EN 13261, and outlines procedures for determining these limits for other steel grades.
• Axle Geometry: Recommends appropriate diameters, shapes, and transitions for various axle sections to optimize performance and extend service life.
• Axle Types Covered: Applies to both solid and hollow axles used in passenger and freight rolling stock across all track gauges.
• Scope of Application: Focuses on rolling stock running under standard European conditions; special applications such as tamping machines have limited design case coverage.

Applications

• Railway Rolling Stock Design: Essential for engineers designing non-powered axles and wheelsets for passenger trains, freight wagons, and locomotives.
• Safety and Compliance: Ensures conformity with EU interoperability directives through stress calculation and dimensional guidelines.
• Material Selection: Guides designers in selecting suitable steel grades and verifying stress limits according to operational requirements.
• Maintenance Planning: Provides a basis for assessing axle integrity and scheduling maintenance to prevent failures.
• Rolling Stock Manufacturers and Suppliers: Offers standardized methods that support product development, quality assurance, and contractual agreements.
• Rail Infrastructure Operators: Enables compatibility assessment of rolling stock with track and gauge requirements.

Related Standards

• EN 13261: Defines steel grades such as EA1N and forms a basis for permissible stress requirements used in EN 13103.
• EN 13104: Covers non-powered axles specifically for motor bogies and locomotives complementing EN 13103’s scope.
• EU Directive 2008/57/EC: This standard supports essential requirements related to railway interoperability across the European Union and EFTA countries.
• Specialized Standards for Light Rail/Tramways: Alternative or agreed documents apply for non-standard track environments, highlighting that EN 13103 focuses on traditional railway systems.
