Structure Performance Numerical Simulation Analysis Of UHPC–steel Combined Type Hybrid Ultra Large Wind Turbine Tower

Wind power is a kind of natural pollution-free renewable resources, it endless, in the faceof global energy pollution and energy crisis, countries are in a large number of research anddevelopment of new pollution-free renewable resources, wind power because of its clean easyto take, rich resources and renewable characteristics, is each country comprehensivedevelopment and use. Our country is wind power resource rich countries, but although thedevelopment potential is very great, but is not complete development and utilization, thereexists the scale is small, the technical level is not advanced defect, and to realize thesustainable development of our country, it is necessary to the scale of the development of newenergy, wind resource is a kind of important energy efficient. To wind in the use of resources,wind power generation is the most direct form, through to the wind energy use to solve theglobal energy crisis is of great significance. Therefore, we must increase efforts to study, theuse of wind power gain more energy.Along with the MW level large wind generating set the height of the development of, asthe wind unit main bearing structure of the tower design research became wind powerdevelopment is an important research content of. Tower directly influence the wind unitstability and overall performance, its strength as wind power generation unit power increases,its characteristic also determines the tower in the simulation analysis and optimization designof the importance of study.This topic to explore new design method and the application of new materials, usinghigh performance fiber modified steel concrete, the application of large finite elementsoftware ABAQUS, bonding strength theory, structure nonlinear theory, structural dynamicsanalysis wind unit tower, the establishment of finite element simulation model, static strengthanalysis, dynamic modal analysis. Research the impact of these factors, and get a conclusion,the results are analyzed and the optimized design for large wind unit tower research providesthe reliable theoretical basis.
