Halbach Square Array Structure for Optimizing Magnetic Adsorption

摘要

To realize reliable adsorption and flexible walking on ships by a multitrack integrated mobile wall-climbing robot, a magnetic adsorption wall-climbing robot is proposed. First, key technologies such as adsorption based on Halbach square arrays are studied. Second, the mathematical model and numerical analysis of the Halbach array are established by the Fourier series method, and adsorption units with different magnetic circuits are compared and analyzed to provide a theoretical basis for the ideal design of adsorption. Finally, the influence of each parameter of the Halbach square array of magnetic adsorption is analyzed by numerical simulation and finite analysis, and the size parameters of the Halbach square array are optimized based on a multi-Island genetic algorithm. The magnetic adsorption volume is nearly double compared to that before optimization. The results prove that the magnetic adsorption of the Halbach square array has significant advantages.
