基于ANSYS风电主轴轴承的强度评估与修形设计
Strength evaluation and modification design of wind turbine main shaft bearing based on ANSYS
摘要
Abstract
In order to address the high maintenance costs caused by premature failure of wind turbine main shaft bearings,a mechanical model of the main shaft double-row tapered roller bearing and a finite element model of the bearing system were established.A finite element-based method for roller profile modification design and strength evaluation of the main shaft bearing was proposed.The load-bearing characteristics of the main shaft bearing under extreme operating conditions were studied,and the accuracy of the method was verified by comparing the theoretical load distribution of the bearing with the results from the finite element model.Finally,the contact characteristics between the rollers and raceways were effectively improved through roller profile modification.The results show that,through roller profile modification design,the contact stress between the rollers and raceways of the fore bearing was reduced by 12.1%,and that of the rear bearing was reduced by 24.7%.The static load safety factors were effectively improved,mitigating stress concentration between the rollers and raceways and enhancing the reliability of the main shaft bearing under extreme operating conditions.This study provides a reference for the design and analysis of main shaft tapered roller bearings.关键词
