NOISE, VIBRATION & HARSHNESS

CIDAUT FOUNDATION

DESCRIPTION AND GOALS OF THE ORGANISATION

CIDAUT Foundation is a private nonprofit institution committed to
strengthening the industrial base in the transport and energy sectors
through specific research and development programs. This center, with
about 250 researchers and technicians, has extensive experience in project
management at regional, national and European level, as has been the
leader of more than 300 research projects since 1993, when it was created.
The Cidaut Foundation has a methodology that allows complete product
development from conception of a new idea, through selection and analysis
of materials, simulation activities, material processing, prototyping and
pre-tasks industrialization to final product validation.

AREAS OF ACTIVITY
t Vibratory comfort for rolling stock t Noise maps for infraestructure
t Interior noise for rolling stock t Solution design for Noise and Vibration reduction

t Exterior noise for rolling stock t Ballast lifting
t Vibration analysis of infrastructures ( track, ...)
