Abstract 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.

交叉滚子钢丝滚道轴承的结构建模：滚子钢丝圈组的分析子模型

摘要 自 1936 年钢丝轴承获得专利以来，它们已被用于以减轻重量为关键方面的应用中。然而，在文献中几乎找不到关于它们结构行为的工作。为了预测钢丝轴承在负载下的反应，最可行的方法是通过有限元 (FE) 对其进行建模和分析。然而，对滚子、线材和滚道之间的复杂接触配置进行正确建模所需的大量元素使得这种方法难以承受。从这个意义上讲，本手稿开发了一个分析子模型，该模型代表了滚子-钢丝-环组的结构行为，以便稍后将其包含在全局有限元模型中，以说明环的柔性和边界条件。这条路，这些复杂区域的计算密集型有限元建模可以被这项工作中开发的分析模型所取代，并且可以使用一个更易于管理的全局有限元模型来预测轴承的结构响应。该分析模型已证明与滚子-钢丝-环组的局部有限元模型非常吻合。
