标题： Structural modeling of crossed roller wire race bearings: analytical submodel for the roller-wire-ring set

摘要： 自1936年滚珠轴承获得专利以来，它们被用于重量节省至关重要的场合。然而，在文献中很少有关于其结构行为的研究。为了预测滚珠轴承在载荷下的反应，最可行的方法是通过有限元（FE）对其进行建模和分析。然而，为了正确模拟滚子、钢丝和滚道之间的复杂接触配置，需要大量的单元，这使得这种方法不可行。在这个意义上，本手稿开发了一个解析子模型，用来表示滚子-钢丝-滚环组的结构行为，以便稍后将其纳入全局有限元模型中，以考虑滚环的灵活性和边界条件。这样，这些复杂区域的计算密集型有限元建模可以由本文开发的解析模型替代，并且可以使用更易于管理的全局有限元模型来预测轴承的结构响应。该解析模型已显示出与滚子-钢丝-滚环组的局部有限元模型的良好一致性。 显示英文摘要

摘要： Since wire bearings were patented in 1936, they have been used in applications where weight saving is a key aspect. Nevertheless, little work can be found in literature regarding their structural behaviour. In order to predict how a wire bearing reacts under load, the most feasible way is to model and analyse it via Finite Elements (FE). However, the great amount of elements needed to properly model the complex contact configuration among rollers, wires and raceways, make this approach unaffordable. In this sense, this manuscript develops an analytical submodel that represents the structural behaviour of the roller-wire-ring set, in order to include it later in a global FE model to account for ring flexibility and boundary conditions. This way, the computationally intensive FE modelling of these complex zones can be substituted by the analytical model developed in this work, and a much manageable global FE model can be used to predict the structural response of the bearing. This analytical model has demonstrated a good agreement with local FE models of the roller-wire-ring set.
