A HIGH-STRENGTH MULTI-PETAL WELDING-FREE STEEL WIND TURBINE TOWER

Abstract

The utility model discloses a high strength multi-lobed weld-free steel wind power tower cylinder including a bottom base flange the top end of which is fixedly installed with several tower cylinder plates several tower cylinder plates are provided with several assembled components each two adjacent assembled components are fixedly connected on their respective sides several assembled components all include a steel plate body two longitudinal connecting pieces and two transverse connecting pieces The utility model a high strength multi-lobed weld-free steel wind power tower cylinder introduces an unequal thickness trapezoidal special shaped plate design based on finite element stress analysis to achieve accurate material distribution and balanced stress transmission using high performance weathering steel as the main structural material to realize the maintenance-free corrosion prevention system "ready for use at factory" completely abandoning the full tower welding process achieving 100% bolted connection for main materials and accessory connections eliminating fatigue weak links from the source and building a truly "fatigue resistant enhanced" structural system to extend the service life of the tower cylinder
