Abstract :
Hub is the key component in the wind turbine. Because of its complex configuration and miscellaneous loading case, it is difficult to simulate its stress value and distribution accurately by utilizing classical mechanics. This paper mainly described the advantages of characteristics of hexahedral element firstly. And then based on the software, stress analysis of hub was carried out. Hub model is meshed as hexahedral elements based on the HYPERMESH software, and strength analysis was done in MSC.Patran / Nastran analysis platform. Finally, it is concluded that hexahedral elements can obtain smoother distribution status and take smaller CPU analysis time in contrast to tetrahedral elements. The results showed that the mechanical strength of hub meet the requirement.
