Aerodynamics simulation (CFD)

Customer: Various customers

Project tasks

​During the development process or during modernisation, aerodynamic influences such as crosswind or vehicle air conditioning of a vehicle must be assessed. Often the final verification requires investigations in a wind tunnel or climatic wind tunnel. However, CFD (Computational fluid dynamics) simulations are ideal for an initial assessment and optimisation, as they generally provide reliable results at significantly lower cost.

Analyses:

  • Crosswind stability (aero-dynamic coefficients and wind characteristics curves) according to EN 14067-6
  • Climatic studies and thermal comfort

Our Approach

Crosswind assessment according to EN 14067-6

The EN 14067-6 provides for the evaluation of crosswind with aerodynamic coefficients, which can be obtained either by wind tunnel tests or by CFD simulations. PROSE can determine these coefficients by CFD simulations and derive characteristic wind curves. The influence of the vehicle design on the crosswind stability can be considered in the design phase. In the case of changes to the vehicle exterior shape during conversions, the influence can be assessed and in the case of minor changes, proof of crosswind stability can also be provided.

Investigation of vehicle air conditioning

CFD simulations allow first estimations for climatic-technical investigations according to European standards, which are based on tests in the climatic wind tunnel. An optimisation with CFD simulations within the scope of the design of the air conditioning system generates additional safety and can avoid costly adjustments and repetitions of measurements in the climatic wind tunnel.

Customer benefit

PROSE can support you during the development process or during a modernisation with CFD simulations to reduce costs and risks of wind tunnel and climatic wind tunnel tests.

  • Development of a project manual applicable to the project

Our Approach

PROSE develops an evaluation matrix based on the VBZ vehicle structure so that it can be determined which measures should be implemented within the framework of R3. The evaluation matrix contains criteria according to which the measures can be evaluated, including an evaluation. PROSE is developing a project manual applicable to the CR3 project. The focus is on the definition of the different phases including their objectives, duration and contents. It also explains which project participants and stakeholders should be involved, when and how, and how responsibilities should be defined.

Customer benefit

The methodology and tooling provided by PROSE in the first phase enables VBZ to efficiently plan and implement Revision 3 and the life extension measures. The evaluation matrix enables VBZ to make informed decisions about which measures should be implemented as part of R3. This helps to use resources effectively and to keep the trams in the best possible condition. The project manual is the basis for VBZ to implement the Cobra tram overhaul and service life extension project in a structured and effective way, resulting in cost savings and efficiency gains.

     

Specifications for emission-free power supply for construction sites

Customer: SBB AG, Switzerland

Project tasks

  • Review and evaluation of the requirements from the specification sheet
  • Discussion and agreement of the commented requirements in a workshop
  • Identification of the requirements that require a risk assessment
  • Creation of a risk assessment
  • Transfer of the requirements into a requirements management system (ReqSuite®)
  • Individual assessment and binding of the requirements

Our Approach

PROSE has drawn up a questionnaire based on these specifications in the sense of “Does a manufacturer have sufficient information? Are the requirements sufficient for the product to be used by SBB”. PROSE checked and evaluated the requirements from the existing specification. The annotated requirements specification was discussed and agreed upon together in a workshop and the requirements requiring a risk assessment were identified. Subsequently, a risk assessment was prepared. The requirements were transferred from the developed basis into a requirements management system (ReqSuite®). The requirements were evaluated individually and given a binding nature in order to evaluate offers received in the subsequent call for tenders.

The requirements specification was then converted into a format that SBB could import into its requirements management system (Polarion®).

Customer benefit

The client received a specification sheet with comments and a supporting questionnaire that allowed him to formulate the requirements more precisely and comprehensibly. Testing, evaluation and identification of requirements that require risk consideration contribute to quality assurance and minimise potential risks in the project. The risk consideration and the binding nature of the requirements enable better preparation for the tender, which improves the quality of the incoming offers. The conversion of the requirements specification into a compatible format for SBB’s requirements management system ensures a smooth integration and use of the requirements by the customer.
