Methods and apparatus for monitoring microrolling processes using embedded sensing

摘要

A method of determining a spatial and temporal pressure distribution profile on an outer surface of a rotating apparatus includes producing one or more pressure indications in response to pressure applied to the outer surface of the rotating apparatus. The producing is carried out by a transducer assembly embedded within the rotating apparatus at a distance d from the outer surface of the rotating apparatus. The method further includes sampling, by an acquisition assembly, the one or more pressure indications from the transducer assembly and storing the sampled one or more pressure indications. The method also includes processing the one or more pressure indications to produce the pressure distribution profile describing the pressure applied to the outer surface.

1. An apparatus configured to rotate, comprising:
a geometric shape disposed about a first longitudinal axis, the geometric shape having a first end, a second end, and an outer surface at a radius r from the longitudinal axis, the geometric shape defining at least one void therein, the at least one void disposed along a second longitudinal axis that is (i) substantially parallel to the first longitudinal axis and (ii) situated between the first longitudinal axis and the outer surface, the at least one void not intersecting the outer surface; and a transducer assembly disposed within the at least one void, the transducer assembly including at least one transducer element constructed and arranged to produce an indication corresponding to pressure distribution applied along the outer surface of the geometric shape.
