Simulation Analysis of Force Fields in High-Power Conductive Slip Rings for Ocean Engineering

The operational stability of high-power conductive slip rings is critical for reliable power transmission and signal integrity in marine equipment such as offshore oil platforms and ships. To investigate mechanical reliability and structural stability, this study establishes a finite element simulation model of a high-power conductive slip ring for ocean engineering and designs a three-factor, four-level orthogonal experiment. Rotational speed, pressure, and friction are selected as the main influencing factors, and their stress sensitivity is determined as rotational speed > pressure > friction. The optimal parameter combination is identified as rotational speed of 5 rpm, pressure of 25 N, and friction of 7 N. Force-field simulation under the optimized conditions shows that the maximum stress occurs at the octagonal section, with a peak value of 304.994 MPa and a maximum displacement of 0.63 mm. The overall stress variation remains within a reasonable range, and structural displacement is small. The body load gradually decreases from outside to inside, consistent with the stress distribution results. The findings indicate that the structure has preliminary mechanical feasibility under the defined electromechanical load cases, while the octagonal stress-concentration region requires attention for long-term durability in high-power electromagnetic systems.
