Origin of Noise EDware – SQUEAK AND RATTLE – Analysis ”The biggest problem in the world could have been solved, when it was small.“ (Lao Tzu) Contact: [email protected] Benefits for the Engineers No change in daily-work condition Updates Latest Improvements Regular Nastran/Abaqus FEModels can be used (NVH & Durability Models) Reading GD&T data from external software like 3DCS or Excel based data for part pair Design for S&R to study Design Feasibility Can read in Six Sigma Results from 3DCS Existing Extended Material Database Contact force point estimation Customization per customer requirements Animation and Shell Expansion in Rattle (in all three directions) Benefits for the Management Clipping points, for Point of Interest Early detection of Squeak and Rattle points before tooling is cut Will help to address “JDPower” and warranty issues by reducing the time needed for testing *Note: Some of the improvements are currently customer specific and are under development. Manufacture for S&R – GD&T Module can be used to control variations of assembly from supplier Non-Linear Module Functions (Linear) The difference between Linear and Non-linear Module being that Non-linear Module can read in Direct Time Domain Currently Non-linear time input can be read and post processed for Abaqus Supports Nastran Linear and Abaqus Linear frequency response solutions Response and ranking is based on impact velocity only SAR index are shown based on ranking by curve or impact velocity System Requirements External factors like GD&T, temperature, surface index can be included CPU >= 2.0 GHz Intel based Material matrix can also be calculated which is internally normalized Video card: nVidia (preferred) >= 128 MB Prerequisites for SAR Model Penetration free FE Model Mechanics (hinge and other mechanisms) to be captured Non Rigid FE Model (clips & snaps not to be represented with rigids) RAM >= 2 GB Min. 5 GB of local hard disk space for scratch files Windows XP Professional or Windows Vista Home/Premium or Commonly available LINUX distributions.
