摘　　要：针对风力发电机塔架底部和基础之间的螺栓联接进行了非线性有限元接触分析。首先根据接触分析的有限元理论建立模型,之后应用BLADED软件计算载荷,得到实际工况下各部件的变形、应力和应变,找出受力最大的螺栓。有限元接触分析结果与理论计算结果吻合,都表明材料的强度满足要求,结构安全。The article mainly refers to the nonlinear contact analysis of bolted joins between the wind turbine tower and the foundation.A model is built first according to contact analysis finite element theory.BLADED software is used to calculate load,and the deformation,stress and strain of the parts are calculated and the maximum stress on the bolts is obtained too.The analysis results by finite element method are consistent with the theoretical calculation results,and the strength of material meets the requirements,which means the structure is safe.
