/ 71 AVL TIPPELMANN ��co����tic ��a��it�� ����ec�� ������te�� ������������ PRINCIPLE Cavities with complicated shapes can ��e e��amined effi ciently using the acoustic cavity inspection system (ACCS) developed and patented by AVL Tippelmann. For this purpose a sound signal is introduced at an opening of the cavity. The transmitted signal is recorded at one or more other openings. Transmission behaviour is essentially determined by the geometry of the cavity. Deviations in phase and frequency response compared to correctly shaped cavities are thus due to geometric errors in the examined cavity. The method is, therefore, suitable for detecting inclusions and full or partial blockages in castings. A typical application is the testing of water jackets in cylinder heads in series production featuring a complex branched and meshed structure. BENEFITS AT A GLANCE • Suitable for complex shaped cavities (e.g. water jackets) • Short cycle times enable 100 �� ��C in serial production • Automated measurement sequence and part evaluation • Robust measurement instrumentation • Low Wear and low maintenance • Low energy consumption
