本文利用互相配合的弹性体配合表面上位移连续条件及力的等值条件建立了计算过盈应力的有限元模型。此模型不仅适用于轴对称结构而且还适用于非轴对称结构。经算例验证具有较高的精度。文中又把该模型推广到同时具有过盈联接和平面接触的组合弹性体上。
In this paper, the finite element model for calculating the interference stress is established by using the displacement continuity condition and the equivalent force condition of the cooperating elastomer. This model is not only suitable for axisymmetric structures but also for non-axisymmetric structures. The example validation with high accuracy. In the paper, the model is extended to a combined elastomer with both interference connection and plane contact.
