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 leads to the understanding of the squeak phenomena using the
characterization shown in Figure 1.Figure 1.
