Noise suppressor designed and used in the railway environment by the staff during the train manufacturing
The noise suppressor is designed and used in the railway environment by the staff during the train manufacturing. The main aim is the hearing protection during the brake tests: only 75 dB against 120 dB for conventional systems. The device has a connector to the compressed air system of the brake circuit, a tap and a release pipe which reduces noise. Except the tap, the parts are carried out in composite materials: fiberglass, para-aramid synthetic fiber (Kevlar®), epoxy resin and a complex absorbing textile glass product. Thanks to the use of composite materials, the tool weighs 800g against 1800g for previous devices. A second version is equipped with a

pressure control that informs the user if the pressure is lower or equal to 7.5 bars, he doesn’t permit the train to leave. The study and development period lasted 4 years, from the manufacture of the first prototype to the first SNCF order. The development was jointly conducted between the railway worker and laboratories of expertise of the SNCF. After 3 tests in different SNCF places, the national authorities of the SNCF decided to provide all French rolling stock. The device is patented by SNCF; TCI has the right to market these attenuators abroad. TCI manufactures, delivers and provides the maintenance of their products.

The market is the railways market: Europe including the Russia and all of its satellite countries. Some devices are testing in Asia, which represents the next market.

Numerical modeling and simulation of a manufacturing process, advising on the performances and costs of the project
The real objective – especially with advanced composite materials – is to predict how critical design and manufacturing parameters (such as material, surface topology, lay-up strategy and ply stacking) impact the behaviour of the final product in terms of performance and cost. Designers currently face the challenge of optimizing the design of composite parts with enough reliable data to justify the necessity of certain design, engineering or manufacturing changes. TruPLAN is a multidisciplinary manufacturing analysis tool that provides designers with the capability to fully model material behaviour during the computation of manufacturing strategies for advanced and automated material deposition methods such as automated tape layer, automated fibre placement and robotics. Engineers can use it to see the impact of initial material and design choices and any in-process changes on the costs of manufacturing and overall lay-up quality. This kernel enables engineers to perform detailed analyses on both the material properties and potential manufacturing processes early in the design stage and throughout the entire production cycle. The goal of each trade-off analysis is to ensure not only maximum production rates, but also manufacturing feasibility by locating and compensating for lay-up defects such as material wrinkling, material buckling, steering, compaction and angle deviation. The data acquired by running TruPLAN will be relevant to any design engineer,
