Analysis of Mechanical Behavior and Optimization Design on the Wind Turbine Blade Maintenance Platform

ZHANG Ke;SONG Enwei;SUN Jia;CHEN Shizhong;LONG Yanze;School of Mechanical Engineering,Shenyang Jianzhu University;  
M echanical behavior of the wind turbine blade maintenance platform was analyzed in this paper. The structure of the platform was optimized basing on the analyzed result,in order to solve the risks of the maintenance of energizing equipments. A 3D model of the platform was established with Solidworks,and imported into ANSYS Workbench to build a FE model. A statics analysis was carried out on ANSYS Workbench to check the stiffness and strength of the platform under three conditions of rated load,partial load and overload. The final design project was confirmed with Solidworks based on the result of topology optimization. The inherent frequency and vibration mode was obtained by extracting the first six order modal. It is found that under the threeconditions,the maximum deformation is 1. 61 mm,the maximum stress is 110. 65 M Pa,which all meet the design requirement. Conclusion is that the the designed wind turbine blade maintenance platform is safe,reliable,conveniently dismantled and ease to transport. Compared with the primary model,the weight of the optimized model reduces by 24. 2%. The proposed method provides references for designs of related products.
