摘要

针对某1.5 MW双馈式风力发电机,利用Ansys的参数化建模语言APDL对其主轴进行参数化建模,得到风机主轴参数化模型以及命令流文件。根据风机主轴的载荷数据,校核了风机主轴在16组极限工况下的静强度,结果显示主轴工作应力在工况dlc 2.1b最大,为237.086 MPa。最大工作应力小于许用极限,主轴符合静强度要求。考虑到实际情况下风机主轴结构尺寸参数、材料力学参数以及所受载荷参数的随机性,利用专门的概率分析软件NESSUS联合Ansys,对风机主轴进行基于静强度的结构可靠性分析,结果显示风机主轴的结构可靠性P,R,=0.999 224 4,略小于要求的0.999 9。根据灵敏度分析结果,提高屈服强度均值,降低屈服强度标准差,提高尺寸参数R,2,均值可增加风机主轴结构可靠度。

Abstract

The parametric FE model of the main shaft for a 1.5 MW doubly-fed wind turbine was established with parametric language APDL of ANSYS in a command stream file. The structural strength of the main shaft under the 16 ultimate load conditions was checked according to the working load data. The results show that the maximum working stress 237.086 MPa found at dlc2.1 b is less than the permissible stress. The main shaft meets the requirement of static strength. In consideration of the randomness of the load parameters, the size parameters and the mechanical property parameters in practical situations, the static strength reliability analysis of the main shaft was executed by professional probabilistic analysis software NESSUS and ANSYS joint simulation. The results show that the structural reliability of the main shaft is 0.999 224 4, which is slightly lower than the required 0.999 9. According to the results of sensitivity analysis, improvement of the structural reliability can be achieved by increasing the mean of yield strength, decreasing the standard deviation of yield strength or increasing the mean of the size parameter R,2,.
