Abstract
A deflection plate for protecting a load cell of a mobile dynamometer, includes a generally elongated member having a front surface, a back surface, a top surface, a bottom surface and two side surfaces. The front surface is at least partially tapered such that the front surface adjacent the top surface is thicker than the front surface adjacent the bottom surface. The taper of said front surface of the deflection plate is preferably dimensioned and configured such that the safety factor along substantially most of its length is at least about 1.1 and less than about 1.2. A method for employing strain gages identifies the magnitudes and locations of loads on slender beams using strain gage based methods with application to portable Army bridges.
Claims20
A deflection plate for protecting a load cell of a mobile dynamometer, comprising:
- a generally elongated member having a front surface, a back surface, a top surface, a bottom surface and two side surfaces;
- said front surface being at least partially tapered such that said front surface adjacent said top surface is thicker than said front surface adjacent said bottom surface;
- said front surface having at least one bore adjacent said top surface;
- and
- said front surface having at least one bore adjacent said bottom surface.
A system, comprising:
- a deflection plate comprising a generally elongated member having a front surface, a back surface, a top surface, a bottom surface and two side surfaces;
- where the deflection plate comprises a beginning segment, a middle segment, and a last segment,
- where the beginning segment terminates at the top surface and is of a first uniform thickness,
- where the middle segment is between the beginning segment and the last segment,
- where the last segment terminates at the bottom surface and is of a second uniform thickness smaller than the first uniform thickness,
- where the front surface of the beginning segment is substantially parallel to the back surface,
- where the front surface of the middle segment at least partially tapers such that at least part of the middle segment is thinner than the beginning segment and such that at least part of the middle segment is thicker than the last segment,
- where the front surface of the last segment is substantially parallel to the back surface,
- where the back surface is substantially flat,
- where the beginning segment has at least one bore, and
- where the last segment has at least one bore.
A system, comprising:
- a deflection plate that comprises a generally elongated member having a front surface, a back surface, a top surface, a bottom surface and two side surfaces;
- where the front surface is at least partially tapered such that the front surface adjacent to the top surface is thicker than the front surface adjacent to the bottom surface,
- where the front surface has at least one bore adjacent to the top surface,
- where the front surface has at least one bore adjacent to the bottom surface, and
- where the deflection place is configured to protect a dynamometer.
