Acoustic Strain Gauge

View page
US Patent:
58082018, Sep 15, 1998
Filed:
Sep 9, 1996
Appl. No.:
8/707922
Inventors:
Monte K. Hugentobler - Novato CA
Assignee:
SonicForce, L.L.C. - Burlingame CA
International Classification:
G01N 2924
US Classification:
73643
Abstract:
Applicant's invention defines an improved electromagnetic acoustic transducer (EMAT) for monitoring stress in an underlying workpiece. The EMATs are provided with positioning pins for fixing the registration of the EMAT relative to the workpiece. The bottom contact surface of the EMAT may be altered geometrically or provided with a friction reducing means, such as a wheel assembly, to minimize contact surface area and thus unwanted frictional influences caused by deformation of the workpiece under the EMAT. An apparatus for reliably positioning the EMATs above a workpiece is also disclosed, said apparatus comprising an actuating means which by a linkage mechanism lowers or raises at least one EMAT into position, further allowing access to the positioning pins for applying the necessary force to anchor the EMATs to the workpiece.

US Patent:
57509000, May 12, 1998
Filed:
Jan 29, 1997
Appl. No.:
8/792695
Inventors:
Monte K. Hugentobler - Novato CA
Efrain Anthony Mandracchia - San Francisco CA
Assignee:
SonicForce, L.L.C. - Burlingame CA
International Classification:
G01N 2924
US Classification:
73779
Abstract:
The present invention defines an improved strain gauge and a method of using an electromagnetic acoustic transducer (EMAT) for monitoring stress and strain in an underlying workpiece. The gauge is provided with positioning pins for fixing the registration of the EMAT relative to the workpiece. The gauge is provided with a friction reducing means, such as a bearing or a wheel assembly, to minimize EMAT bottom contact surface area and thus unwanted frictional influences caused by deformation of the workpiece under the EMAT. An assembly for reliably positioning the EMAT gauge above a workpiece is also disclosed, in which the assembly comprises an actuating means which by a linkage mechanism lowers or raises at least the EMAT into position, further allowing access to the positioning pins for applying the necessary force to fix the position of the gauge relative to the workpiece.
