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.
