Expanded material database improves squeak and rattle tests

0

Altair has partnered with Ziegler-Instruments to enhance its Squeak and Rattle Director (SnRD) for NVH prediction. The addition of Ziegler-Instruments’ PEM material database gives Altair’s SnRD clients access to the results for over 11,000 individual stick and slip phenomena for different material pairs. 

The SnRD is a combination of highly customized software and automated processes that are implemented by Altair’s service division, Altair ProductDesign, in conjunction with a client’s engineering and testing teams. The solution creates a comprehensive, efficient and semi-automated approach to determine relative component displacements in the time domain that can lead to undesired squeaking and rattling in products.

Uniquely designed to be deeply integrated within a company’s existing work environment and processes by the Altair product design team, the SnRD offers a comprehensive methodology to streamline the entire squeak and rattle simulation workflow process from model creation to results visualization.

“The Squeak and Rattle Director allows us to input different data, like design and manufacturing tolerances, in order to improve the output of our analysis and therefore have more valuable input into the project,” said Marcelo Starling Braga, NVH coordinator, Fiat Brazil.
