摘要

The marine riser bears various power loads during operation. We designed the Quadrupole-type magnetic measurement probe based on the inverse magnetostrictive effect (the impact of stress on the magnetization) and performed finite element simulation and experimental analysis. The results of both the finite element analysis and magnetic measurement basically follow the same trend, so we conclude that this four-pole magnetic probe measurement can quantitatively evaluate the force state in a marine riser.
