Vibroacoustic engineer

Req ID:454755 

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.
