| 摘 要： | 本文在轴对称不稳定热传导有限元分析模型的基础上,提出了一个内燃机燃烧室的活塞与缸套偶合系统的不稳定传热数值分析模型。该模型考虑了在燃气与边界的对流和热幅射非线性热交换条件下运动着的活塞、活塞环、缸套和润滑油膜之间在传热过程中的相互作用和影响,可以预测上述系统各部分的温度波动分布、瞬态温度场以及瞬态热流分布。

| Abstract: | Based on an axi-symmetric unsteady conduction model by FEM, a numerical analysis model of unsteady heat transfer for the piston-liner coupling system of combustion chamber in an I. C. engine is proposed. The model can be used to study the heat transfer process in the piston rings-oil film-liner-coolant system under actual convection and radiation conditions in the combustion chamber and to predict the temperature fluctuation and instantaneous temperature field distribution in the system. |
