Three Ways That the Acoustic Influence Map Is Better
Source: Evident
Since the Acoustic Influence Map (AIM) modeling tool was introduced with the launch of the OmniScan™ X3 flaw detector, it has become an integral assistance tool for the design of total focusing method (TFM) scan plans. AIM provides an estimate of the TFM acoustic intensity coverage for different TFM wave sets and scatterer types, enabling you to create a scan plan that maximizes the probability of detection (POD).

With the release of MXU 5.10, you’ll benefit from three major upgrades to AIM that further enhance the capabilities and ease-of-use of the OmniScan X3 and X3 64 scan plan tool.

Previously, AIM only supported linear probes for which the TFM inspection area is directly below the primary axis of the elements. Now with the MXU 5.10 update, AIM supports Dual Linear Array™ (DLA) and Dual Matrix Array™ (DMA) probes for planar, circumferential outside diameter (COD) and axial outside diameter (AOD) geometries. This change is enabled by a major overhaul of the fundamental framework of the AIM model.

The updated AIM model provides similar results to some other commercial acoustic simulation software packages. For example, compare the below images generated by the updated AIM model and the sensitivity map obtained from CIVA 2021 (developed by CEA LIST) for the L-L TFM wave set on an AOD geometry.
