Squeak and Rattle Director Tutorials

SnRD can be used to evaluate and study squeak and rattle issues in various products and across many industries. Some of the typical usecase are:
  • Risk and Root Cause (Dynamic) Analysis: evaluating squeak and rattle issues on a model for dynamic/transient loading condition.
  • Quality Feel (Static) Analysis: evaluating squeak and rattle issues on a model for static/touch point locations.
  • Driving the vehicle exposed to thermal effects: evaluating squeak and rattle issues on system, when imposed with multiple loading conditions. For example, a vehicle is parked under direct sunlight and is driven off.
  • Manufacturing Variations study: to forecast the squeak and rattle issues in the systems based on the manufacturing variations like, component thickness, attachment stiffness, modal damping, and so on.
