We create smart innovations to meet the mobility challenges of today and tomorrow. We design and manufacture a complete range of transportation systems, from high-speed trains to electric buses and driverless trains, as well as infrastructure, signalling and digital mobility solutions. Joining us means joining a truly global community of people dedicated to solving real-world mobility challenges and achieving international projects with sustainable local impact.
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 Components
Responsibilities
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.
