Squeak and Rattle Director

Altair's Squeak and Rattle Director (SnRD) is a novel set of software automations to rapidly identify and analyze design alternatives to eliminate the root causes of squeak and rattle (S&R) in assemblies. Tailored to be deeply integrated within your environment and processes, SnRD offers a complete set of capabilities to streamline the entire S&R simulation workflow process from model creation to results visualization. Fully integrated in the HyperMesh and HyperView, this user-friendly solution provides a highly semi-automated approach to determine relative component displacements in the time domain that can lead to undesired squeaking and rattling in products. By identifying potential areas of concern in the early stages of design, the overall design quality can be improved and significant cost and time savings can be realized.

What Users Say

 
Quote
"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 inputs to the project.”
–Marcelo Starling Braga,
NVH Coordinator at FIAT Brazil

优势

  • Identifies risk zones for squeak and rattle from the earliest development phase when no prototype is available from correlation to test support
  • Automates repetitive pre and post-processing calculations and presents results in a standardized format
  • Diagnosis module to perform Root Cause Analysis & Sensitivity Analysis without re-running the model
  • Prediction of Rattle occurrence using design criteria like GD&T data
  • Prediction of stick-slip phenomena for different materials thanks to a seamless integration of Ziegler PEM Database
  • Decreases the time to perform squeak and rattle analysis by up to 80%

Ideal for Organizations that:

  • Serve markets where quality and value are tightly coupled with the perceptions of Squeak and Rattle
