Abstract:With the increase of detection and maintenance work in the wind turbine, in order to reduce the labor intensity of workers, a new type of wall climbing robot on the wind turbine is designed for detection and maintenance tasks. The practical significance of wall climbing robot on the wind turbine to detect and maintain was analyzed, the design of technical index and route were made, and the basic function scheme was analyzed mainly. Finally, the structure of basic machine of robot was designed. In order to avoid losing efficacy of adsorption, the robot mechanical models in some dangerous situation at the wind turbine were established, such as slipping, overturn and the leaked suction cups. The result is simulated analysis with MATLAB, identified the security adsorption of critical adsorption. So that it can provide the basis for the determination of adsorption force of the suction cups of robots.
