Ultrasound inspection system and ultrasonic quality control method

摘要

An ultrasound inspection roller provided with a wheel, a sensing system and a support for holding the sensing system inside the wheel, a wedge connected to the ultrasound sensing system at one end and provided with a curved profile at its other end facing the wheel, adapted to the curvilinear shape of the wheel, and a liquid of a density higher than 9.9*102 kg/mm3 placed inside the wheel such that the sensory system, the wheel and the wedge are acoustically coupled. The roller allows the early detection of problems during manufacturing of composites and the performance of corrective measures in real time, and assures a good coupling between the transducers and the material to be inspected in dry conditions.

1. An ultrasound inspection roller provided with a wheel comprising:
at least at its cover, a deformable material, an ultrasound sensing system and a support for holding the sensing system inside the wheel, the ultrasound system further comprises a wedge connected to the ultrasound sensing system at one end and provided with a curved profile at its other end facing the wheel, configured to the curvilinear shape of the wheel, and a liquid placed inside the wheel such that the sensory system, the wheel and the wedge are acoustically couple, wherein the thickness of the wheel, Er, thickness of a part to be inspected, Ep, and the thickness of the wedge, Ec, follow the following relationships:
Er>Vr/Vp*Ep Ec>2*Vc/Vp*Ep wherein, Vr is the propagating speed of the wave in the wheel; Vp is the wave's propagating speed in the part, and Vc the speed in the wedge.
