摘要:
基于ABAQUS建立转盘轴承对数修形滚子与滚道接触的局部有限元模型,分析对数修形滚子在滚动和滑动工况下转盘轴承的应力分布。结果表明:随滚动和滑动的速度增加,应力分布趋势相同,但应力值变化不大,可以忽略速度对应力分布的影响。载荷较小时,滚道上应力分布均匀。载荷较大时,滚子端部与滚道接触位置应力明显增加。随载荷增加,模型整体应力值变大。摩擦因数增加,滚道上应力分布均匀,等效应力和接触应力变化不大,交变应力变大,且最大交变应力向滚道表面移动。
Abstract:
The finite element model of the roller and raceway of the slewing bearing was established by ABAQUS.The influence of the roller and the sliding condition on the bearing capacity of the turntable bearing was analyzed.Results showed that the velocity of rolling and sliding increases and the stress distribution tended to be the same,but the stress value did not change greatly,and the effect of velocity on the bearing capacity could be neglected.When the load was small,the load distribution on the raceway was uniform,and when the load was large,the stress at the end of the roller and the raceway was increased obviously.As the load increased,the overall stress value of the model became larger.When the friction coefficient increased,the load distribution on the raceway was uniform,the equivalent stress and the contact stress changed little,and when the alternating stress became larger,and the maximum alternating stress moved to the raceway surface.
