| Abstract: | Using large finite element software MSC.Marc/Mentat,the contact analysis of bolted joints parts between the hub and the bearing of wind turbine is conducted for the contact stress suffering from the practical work load.The maximum stress acted on the bolt is obtained,and a detail contact analysis for this bolted joints parts is given.The accurate stress of bolts,bearing and hub is calculated.The FEA contact results are consistent with the theoretical calculation results,and the strength of materials meets t... |
