Abstract:
1. A method of testing a structural component having a complex surface contour by means of ultrasound, comprising the steps of: guiding at least one ultrasonic head by means of a manipulator having a plurality axial drives along a plurality of axes at a defined spacing along the surface contour of the structural component, according to the movement of at least one drive, generating equidistant pulses as trigger signals for geometrically correct allocation of received ultrasonic test data for the surface contour of the structural component, calculating a length of a surface line reproducing the surface contour, calculating support points for guiding the ultrasonic head, moving the axial drives of the manipulator synchronously along the predetermined support points, and controlling a trigger drive in synchronism with the axial drives and, together with all engaged axial drives, displacing the trigger drive in accordance with the predetermined surface line, the trigger drive being notionally guided by the surface line and equidistant trigger pulses being generated relative to the surface line.
