DISPOSITIVO MOBILE PER GENERARE DELLE ONDE ACUSTICHE TRASVERSALI |
摘要 |
<p>A mobile device is used which includes a target-member adapted for coupling to the earth and a means for striking the target- member so as to generate acoustic shear waves. The target-member is coupled to the earth through a deformable coupling member secured to the rigid frame of the target- member, the coupling being enhanced by the combination of a suction means and a network of channels arranged on the face of the coupling member which is in contact with the earth, whereby a partial vacuum is created between the coupling member and the earth.</p> |
