活塞-气缸系统的摩擦动力学性能受多种物理场的影响。本文提出了一种新的多物理场耦合方法，对考虑缸套振动的活塞裙-缸套润滑界面进行建模和分析。该方法通过耦合曲柄连杆活塞缸系统的多体动力学、气缸和活塞的传热、裙部-气缸界面的流体动力润滑、缸套的振动、活塞缸系统的热变形和弹性变形以及润滑油的流变特性来实现。将该方法应用于某四冲程汽油机的动力学和摩擦学特性预测，揭示了缸套振动对活塞-气缸系统摩擦动力学实现的影响。结果表明，增大气缸的刚度和阻尼系数有利于抑制系统的振动，但对活塞裙-气缸接触面的摩擦学特性影响不大。
The tribo-dynamics performance of the piston–cylinder system is affected by multiple physical fields. The current work presents a novel multiphysics coupling method to model and analyze the lubricated piston skirt–cylinder interface considering the cylinder liner vibration. This method is implemented by coupling multibody dynamics of the crank-connecting rod–piston–cylinder system, the heat transfer of the cylinder and piston, hydrodynamics lubrication on the skirt–cylinder interface, vibration of the cylinder liner, and thermal as well as elastic deformation in the piston–cylinder system together with rheological characteristics of lubricating oil. The proposed method is adopted into a four-stroke gasoline engine to predict its dynamics and tribological characteristics, with the purpose of revealing the influence of cylinder liner vibration on the tribo-dynamics implementation of the piston–cylinder system. The results indicate that increasing the stiffness and damping coefficient of the cylinder is beneficial to suppress the vibration of the system, but it has little effect on the tribological characteristics of the piston skirt–cylinder interface.
