Abstract
A measurement apparatus for determining a bending moment acting on a hollow cylindrical body in a current state as well as to a method of operating such a measurement apparatus. The measurement apparatus may include a sensor support structure, a sensor arrangement with sensors, and a processing system. The processing system may determine displacements of the inner surface of the hollow cylindrical body relative to the sensors based on the distances measured in the current state compared to the distances measured during an initial undeformed state, and determine the bending moment acting on the hollow cylindrical body based on the displacements.
Claims15
A measurement apparatus for determining a bending moment acting on a hollow cylindrical body, the hollow cylindrical body having an inner surface, comprising:
- a sensor support structure that is inside the hollow cylindrical body without being in contact with the inner surface;
- a sensor arrangement that is mounted to the sensor support structure and comprises at least first and second sensors that measure first and second distances in first and second directions between the first and second sensors and the inner surface;
- and
- a processing system that determines first and second displacements of the inner surface relative to the first and second sensors based on the first and second distances measured in a current state compared to the first and second distances measured during an initial undeformed state, and determines the bending moment acting on the hollow cylindrical body based on the first and second displacements.
