Rail Engineering / Systems Assurance

Rail Engineering and System Assurance

BMT delivers practical technical expertise, providing through-life engineering support from concept design and construction, through operations and life extensions/upgrades.

Ensuring that best practices from all business sectors are transferred, where feasible, into the rail industry around the world. System Assurance has been widely adopted to assure systems engineering processes and products conform to requirements for operational safety, reliability, availability, maintainability, National & International standards, procedures and regulations.

Specification and Design Review

MSCT_Design ReviewThrough our extensive experience in the development of technical specifications and completing design reviews on wagons, passenger vehicles and sub-systems, we assist purchasers of new railway assets through a specification and design review process. We can contribute to the technical specification of the assets to be purchased; and after the contractor has been selected, we undertake a detailed design review to ensure the specified mechanical and structural requirements have been achieved in the final design. The specification and design review process provides very high value by avoiding costly design oversights.

These services are provided by our specialist operating companies in Australia, Canada and the UK.

Structural and Detail Analysis

MSCT_Design AnalysisOur Test, Measurement and Analysis team have extensive experience measuring strains, accelerations and displacements on rail vehicles and structures facilitating structural redesign, fatigue evaluation, load case definition and compliance with collision and impact loads in line with Collision Code Compliance.

Technical Feasibility and Fitness-For-Service Assessment

BMT uses the collective experience of our engineering team in combination with a practical understanding of the operational environment to assess proposed changes to vehicles or track side equipment.

These services are provided by our specialist operating companies in Australia,
Hong Kong and the UK.

MSCT_Welding EngineeringStructural Integrity Assessment, Welding Engineering Services and Design

BMT provides guidance for the repair of damaged vehicles, weld specification and assessment to achieve the desired fatigue or strength requirements.

These services are provided by our specialist operating companies in Australia and
Canada.

Failure Investigation, Design of Life Extension Modifications

BMT has conducted various types of failure investigations within the rail industry; from wheel failures and noisy brake equipment in Canada to bearing failures in the UK. Utilising our wide technical experience we have developed suitable solutions for our customers to improve reliability of components and availability of assets.
BMT has supported our customers in optimising their maintenance plans and reducing the overall cost of maintenance by utilising various techniques, including Reliability Centred Maintenance (RCM).

These services are provided by our specialist operating companies in Australia,
Canada and the UK.

Prototype Stress and Deformation Acceptance Testing

BMT has completed numerous static and semi-static trials on wagons, passenger cars and locomotives. Our work in this field has included comparisons to Finite Element Analyst (FEA) to assess the modelling strategies and conclusions. We have developed in-house instrumentation for this testing and can competently carry out testing anywhere in the world.

Ride Quality Analysis and Testing

MSCT_Ride Quality

We have completed ride quality testing
on passenger cars, locomotives, and
ride performance tests on wagons.
We have used this data to guide the
tuning of bogie suspension and identify causes for poor ride performance.
We understand this environment and
have a good understanding of the pitfalls and requirements of ride quality testing and analysis.

These services are provided by our specialist operating company in Australia.

Internal and External Aerodynamics, Computational Fluid Dynamics (CFD) Analysis

Using advanced CFD analysis techniques BMT undertakes pre-production modelling of airflows inside passenger cars as well as external aerodynamics.

These services are provided by our specialist operating companies in Australia
and the UK.

Reliability Engineering

Whilst reliability targets may form part of the design/contractual requirement, reliability prediction (modelling) on the whole system, using calculations based on assumed component failure rates and repair rates, provides an early indication of whether the proposed design/components meet the design requirements. Comparisons of different design options can then be made and alterations to components, maintenance or spares holding strategy can then follow.

More importantly, it offers failure information, which could be fed back to modify the maintenance/spare strategy and also to provide reliability growth for revising the design through modification. Our team is fully experienced in all aspects of ARM including:

  • Failure Modes, Effects and Criticality Analysis (FMECA);
  • Reliability prediction using various techniques such as PSM/PCM (Parts Stress/Count
    Method);
  • Fault Tree and Event Tree Analysis and Reliability Block Diagrams; and
  • Maintenance and maintainability studies such as Maintenance Requirement Analysis, and Reliability/ Maintainability Demonstration using different test plans such as fixed time or sequential.

These services are provided by our specialist operating company in the UK.

Electromagnetic Compatibility (EMC) Review and Management

MSCT_Radiated Emissions Test

EMC analysis assures that the various railway sub-systems remain compatible between themselves and the environment to prevent potentially hazardous errors and misoperation.
EMC management begins with the development of an EMC Management Plan. It follows with the identification of potential EMI hazards within the premises, assessing the EMC performance required for the design of the system / sub-system / equipment including all necessary control measures, verifying the EMC performance of individual equipment procured and reviewing the overall design of the system / sub-system to ensure all EMC issues identified have been addressed.
BMT also assists customers in identifying the tests that must be carried out in order to verify EMC performance. This helps to identify where, if any, performance flaws exist and form the basis for further control measures or design modifications.
