What is BS EN 13103-1 - Axles with external journals about?
BS EN 13103 discusses wheelsets and bogies in railways. BS EN 13103-1 is a European standard that provides a design method for axles with external journals in wheelsets and bogies in railways.
BS EN 13103-1 is the first part of a multi-part series that:
- Defines the forces and moments to be taken into account concerning masses, traction, and braking conditions
- Gives the stress calculation method for axles with outside axle journals
- Specifies the maximum permissible stresses to be assumed in calculations for steel grade EA1N, EA1T, and EA4T defined in EN 13261
- Describes the method for determination of the maximum permissible stresses for other steel-grades
- Determines the diameters for the various sections of the axle and recommends the preferred shapes and transitions to ensure adequate service performance
BS EN 13103-1 applies to axles defined in EN 13261, powered and non-powered axles and all truck gauges. BS EN 13103-1 also applies to axles fitted to rolling stock intended to run under normal European conditions.
The powered axle design method of BS EN 13103-1 applies to solid and hollow powered axles for railway rolling stock, solid, and hollow non-powered axles of motor bogies, and solid and hollow non-powered axles of locomotives.
Who is BS EN 13103-1 - Axles with external journals for?
BS EN 13103-1 on a design method for axles with external journals railway applications is useful for:
- Axles manufacturers
- Test centers for axles with external journals
- Maintenance staff for axles with external journals
- Regulatory authorities
Why should you use BS EN 13103-1 - Axles with external journals?
Many years ago, specific dimensioning methods were developed to design axles. They were based on a feedback process from the service behavior of axles combined with the examination of failures and on fatigue tests conducted in the laboratory, to characterize and optimize the design and materials used for axles.
BS EN 13103-1 guideline assists you with forces to be taken into consideration, moments to be taken into consideration, determination of geometric characteristics of the various parts of the axle, and maximum permissible stresses method for axles with external journals railway applications.
This encourages the user to standardize the quality of axles with external journals and ensure the safety of passengers by minimizing the hazards.
