The Research of Finite Element Modeling and Contacts for Connecting Bolts of Wind Turbine

Abstract:

Combined with characteristics of wind turbine bolt connection structure, with the connection of pitch bearing inner ring and the blade root as the research object, through the finite element analysis software Ansys, establish various connection model, using the multiple point coupling constraint and nonlinear contact for finite element analysis , research on bolt truss element types, connections of each component and the establishment of contact, then obtain and analysis affects of finite element calculation with different element types of bolt truss ,contact relationship ,compared with theoretical results, put forward feasible finite element analysis scheme of wind turbine bolt connection, and provide basis for the structure design and intensity analysis.
