Trèves Products Services & Innovation in France is one of the leading Tier-1 suppliers of noise, vibration, and harshness (NVH) reduction parts, providing full sound packages for the trunk, body, interior, and powertrain. To best meet their customer expectations, where possible, Trèves reduces part design and lead time by replacing expensive and time-consuming physical testing with numerical modeling. Traditionally, such models need real parts to account for their multi-layer arrangement and varying thickness, with readily available input parameters. They also need to be comprehensive in scope and easy to implement.

Available via the Altair Partner Alliance (APA), AlphaCell from Matelys-Research Lab offers several features that meets Trèves’ needs, and have helped position Trèves to provide robust solutions to OEMs in order to achieve the next generation of pass-by noise limits.

The Sound of Silence -  Acoustic Analysis of a Rail Carriage Bellow using Product Alphacell

The Sound of Silence - Acoustic Analysis of a Rail Carriage Bellow using Product Alphacell

Noise reduction is an important issue when developing products and components for railway applications. Recently, Ultimate Europe had to perform an acoustic analysis of a rail carriage bellow. In addition to its own broad portfolio of simulation solutions, Altair offers a wide selection of complementary software tools through the Altair Partner Alliance (APA). With Altair’s unique, flexible licensing model customers have access to these solutions at no additional costs. Altair Units allowed Ultimate to leverage APA products and access the functionalities of AlphaCell to predict the acoustic response of the bellow. Results included reduced run time, a decrease in model set up time, and increased combined metric correlation.
