Altair has partnered with Ziegler-Instruments to enhance its Squeak and Rattle Director (SnRD), making it the most advanced and comprehensive solution on the market to predict and eradicate squeak and rattle phenomena in vehicles, aircraft and other products sensitive to Noise, Vibration and Harshness (NVH). 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 materials pairs.

Watch this 40 minute session to see live how the SnRD can accelerate the virtual testing process, reduce the reliance on physical tests and add value to current vehicle development programs.


Highlights include:

  • Identifies risk zones for squeak and rattle from the earliest development phase to correlation and test support
  • Provides a consistent and efficient method to set up the simulation models
  • Automates repetitive pre and post-processing calculations and presents in a standardized format
  • Results for over 11,000 individual stick-slip measurement steps
  • Prediction of stick-slip phenomena for different materials
  • Decreases the time to perform squeak and rattle analysis by 80%

Suitable for:
Engineering managers and team leaders who are involved with the identification of squeak & rattle in vehicle interiors.
