Wind Turbine Self-Advancing Access System And Its Lightweignt Design

With the rapid growth in energy consumption as well as the high pollution and the high cost of traditional fossil energy since the industrial revolution, wind power has become an important part of the world’s energy. The Wind Turbine Self-lifting Access System was researched in this paper for the requirements for wind turbine maintenance. It was able to complete the task of access to the wind turbine by climbing up from the bottom of the wind turbine.The theoretical basis of the Wind Turbine Self-lifting Access System was basis on domestic and foreign excellent wall-climbing robot principles. With systematic analysis the development status of wall-climbing robot and wind turbine maintenance in domestic and foreign, the movement of wall-climbing robot, and the close to the task specific working conditions of wind turbine access, proposed two specific programs and choose one of it. Through three-dimensional software get The Wind Turbine Self-lifting Access System three-dimensional modeling; Stress analysis of key components in order to improve the security and efficiency and lightweight, at the same time structural improvements for it, and re-analyzed it to determine if the improvement is effective.The main difficulties in the structure of Wind Turbine Self-lifting Access System are closed to the main body design, magnetic adsorption structure design. Solution:use of the magnetic force for the body structure design, lightweight and flexible degree of Wind Turbine Self-lifting Access System is to maximize the improvement and ensure the adsorption force.The lightweight of car frame is the key issue of Wind Turbine Self-lifting Access lightweight design. Using the lightweight design method to determine the car frame in the certain material circumstances; the lightweight operating not only reduced the stress and deformation of the car frame effectively, but also reduced the6.25%of its weight.
