摘 要: An existing model for the dynamic analysis of the piston motion in an internal combustion engine has been modified to incorporate a simpler representation of the piston-cylinder interaction, and to represent the main and big-end bearings as lubricated rather than dry journal bearings. The results demonstrate that the differences in calculated bearing forces and output torques are negligible, indicating that the simple dry journal bearing model is sufficient, but show that the modelling of the interaction between piston and cylinder is considerably improved.

对内燃机活塞运动的动态分析现有模型进行了修改,以更简化的形式表示活塞与气缸之间的相互作用,并将主轴承和大端轴承建模为润滑式而非干式轴瓦。结果表明,计算出的轴承力和输出扭矩的差异可忽略不计,说明简单的干式轴瓦模型已足够; 同时,活塞与气缸之间相互作用的建模得到了显著改善。
