中文摘要：

应用专用软件AVL_EXCITE Piston＆Rings对活塞环的动力学特性进行了分析,建立了计及活塞环与气缸套之间的流体动力润滑的活塞环动力学模型,计算出发动机运转过程中活塞环与气缸套间的接触力,据此对气缸套的磨损进行预测。预测结果与某些文献中的测试结果基本一致。

英文摘要：

The dynamics characteristics of piston ring are analyzed by using proprietary software AVL_EX- CITE Piston ＆ Rings. A dynamics model for piston ring is set up with consideration of fluid dynamic lubrication be- tween piston ring and cylinder liner. The contact forces between piston ring and cylinder liner are then calculated, based on which the wear of cylinder liner is predicted with its results basically agree with that of tests presented in some literatures.
