摘要
在选定润滑油品、给定轧制速度和轧制压力的情况下,利用大型有限元分析软件ANSYS对油膜轴承和润滑油膜进行双向流固耦合分析,计算分析了考虑温度变化的不同相对间隙时的油膜及衬套的受力变形情况,得到了衬套受力变形及温度分布规律,并利用疲劳极限求出轴承的最佳相对间隙,为轴承结构优化提供理论数据。
Under the given lubricating oil, rolling speed and rolling pressure, the finite element analysis software ANSYS was used to analyze the lubricating oil film and bearing by two-way fluid-to-solid coupling method, and the deformation and force of oil film and bushing with different relative clearances were calculated, as well as those with consideration of oil film temperature. Moreover, the fatigue limit theory was used to obtain the best relative clearance, which can provide theoretical data to the bearing structure optimization.
