为了避免故障和确定液压密封的维护间隔，有必要预测在使用寿命期间的任何泄漏。然而，平动密封的泄漏与动密封接触中的接触压力分布密切相关，因此与密封边缘的持续磨损密切相关。本文采用Archard磨损模型，模拟了摩擦、液膜和磨损之间的相互依赖关系。流体膜的计算采用雷诺方程，固体接触采用佩尔松模型。与实验结果的比较表明，不仅对磨损面积，而且对磨损表面的精确几何形状都有很好的一致性。
In order to avoid failures and to define maintenance intervals of hydraulic seals, it is necessary to predict any leakage during lifetime operation. However, the leakage of translational seals is closely connected to the contact pressure distribution in the dynamic sealing contact and therefore to the continuing wear of the sealing edge. In this paper the mutual dependency of friction, fluid film and wear is simulated employing the wear model of Archard. The calculation of the fluid film is based on the Reynolds equation, while the model of Persson is applied for the solid contact. A comparison with experimental findings reveals a good agreement not only for the worn area, but especially for the exact geometry of the worn surfaces.
