Abstract: The icing of overhead ground wires can cause various electrical and mechanical accidents, and the use of deicing devices can effectively deice the ground wires. In order to improve the stability of the ground wire deicing device, this paper optimizes the structural parameters of the clamping wheel mechanism of a certain ground wire deicing device. With the goal of maximizing the contact stiffness of the clamping wheel, finite element analysis method is used to first calculate the sample points and build a support vector regression approximation model. Then, the second-generation non dominated sorting genetic algorithm is used for optimization to obtain the optimal clamping wheel structural parameters. Finally, simulation and experimental comparison verification are carried out. The results indicate that the optimized clamping wheel has good adaptability and clamping ability, improving the stability of the deicing device.
