Rattle Evaluation
The rattle evaluation is based on the assessment of relative displacement between two parts along the defined E-Line. The relative displacement is compared to the Gap and Tolerance values defined during the pre-processing workflow.
- Relative displacement magnitude and in local Z-direction
- Dynamic Tolerance is defined as: Gap [mm] - Tolerance [mm] - Relative Displacement in Z
- Soft - foam, leather, rubber, and so on.. materials - default
Youngs(E) Modulus < 500 MPa
- Medium - soft plastics material -
501 MPa < E-modulus < 10000 MPa
- Hard - hard plastics, metals, glass materials -
E-modulus > 10000 MPa
Issue and risk areas are then easily identified, guiding the analyst for deeper investigation of root cause and problem solving.
