The squeak evaluation is based on the contact plane relative displacement. As per the
E-Line method definition, in X and Y local Direction. The Max Relative Peak to Peak
amplitudes, also called MAX Principal Peak to Peak (MAX Principal P2P), are compared to
the inverse of Impulse Rate [mm] (IR-1) values from the specific pair of materials along
each E-Line.
The automatic assessment allows the understanding of the squeak phenomena using the
following characterization: Figure 1.
