Design and mechanical analysis of wall-climbing ROV adsorption structure

This paper studies the design and reliability of a wheeled walking structure based on electromagnets for remotely operated underwater vehicles (ROV). First, the walking structure is based on the traditional wheeled structure and combined with electromagnet adsorption technology. It has the advantages of high adsorption reliability, controllable adsorption strength, and convenient separation from the magnetic wall. In addition, the safety of the designed structure in different adjacent states is mechanically analyzed to obtain the minimum feasible adsorption force. At the same time, the influence of the current input of the electromagnet on the adsorption capacity is explored through simulation. Finally, a set of mechanical experiments are conducted to verify the effectiveness of the design scheme and obtain a set of feasible design schemes.
