Date: 17 nov. 2022

Lieu: Crespin, FR

Entreprise: Alstom

In the context of Product Engineering development, a Vibroacoustic engineer will participate in project/offer development through the application of internal procedures including Vibroacoustic management of projects, standard Vibroacoustic simulation and measurements of Rolling Stock and Components In case of assignment to R&D tasks, he will be in charge of the development of methodologies and technologies related to Vibroacoustics of Rolling Stock and Component

Position in the Organisation:

Organisation Reporting Hierarchical to Acoustic Chief Engineer/Acoustics CCN Leader for engineers based in Central Engineering. Hierarchical to TDE for engineers based in integrator sites and component sites. Functional to Acoustic Chief engineer/Acoustic CCN Leader, PrEM and Technical Bid Engineering Manager




Projects main missions

To apply the Vibroacoustic Engineering Instructions and guidelines to perform the project/offers tasks

To perform the Vibroacoustic analysis of tenders by comparison with referent solutions and previous projects

To Prepare the Vibroacoustic specifications and Vibroacoustic Management Plan (VAMP) to be applied in projects

To choose the most efficient way to perform the allocation (experimental/numerical), verification and validation during tender and project phase

To allocate the different noise sources and train assemblies through the use of AT standard methodologies.

To perform standard Vibroacoustics tests, to postprocess the data and report to validate prediction models and type tests

To perform standard Vibroacoustic simulations for exterior noise and interior noise using inhouse developed tools

To liaise with the Acoustic Chief Engineer to validate Management Plan, allocations and risks.

To liaise with experts in key domains to obtain the necessary data to perform the allocation

To liaise with acoustic engineers in other sites and to use AT Vibroacoustic databases to obtain the necessary REX to perform the allocations

To capture the Vibroacoustic REX of projects through the use of AT Vibroacoustic databases


R&D main missions*

To lead and manage R&D actions in the context of product improvement and/or methodologies for Vibroacoustics for Rolling Stock. This includes management of resources and budget respecting the quality, cost and delay of R&D deliverables. To develop innovative methodologies to be applied as a standard in the design process of rolling stock. *if assigned to R&D missions

Knowledge & Experience :

Engineering degree (BSc/MSc) or physicist with specialization in Vibroacoustics, acoustics, vibration, NVH.
