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,. I.e 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, etc.
