四川理工大学毕业设计（论文） 气缸盖三维建模及其冷却水道的CFD流场分析 摘 要 本文以单缸柴油机的气缸盖为研究对象，利用Solidworks三维软件建立气缸盖几何模型。然后使用Solidworks中的插件Floworks对气缸盖的冷却水道进行流场分析。分析主要从从温度场、压力场和冷却液的流速三个方面进行。 由分析可知该单缸柴油机气缸盖冷却水套的设计比较合理，并能达到设计要求的冷却效果，但是也存在一些需要优化的地方，需进一步改进，以达到最优的冷却效果。 通过对内燃机气缸盖冷却水道的三维CFD数值模拟，得到了大量的水道流场信息，为指导该单缸气缸盖冷却水道的开发设计和改进提供一定的理论依据。 关键词：气缸盖；冷却水道；温度场；CFD数值模拟 ABSTRACT Based on the single cylinder diesel engine cylinder head as the research object, using Solidworks 3D software is built cylinder geometric model. Then use Floworks Solidworks of plug-in for cylinder head cooling channels for flow field analysis. Analysis of the temperature field, mainly from pressure field and cooling fluid velocity of the three aspects. By analyzing the single cylinder diesel engines that the design of cylinder head cooling water is reasonable, and can meet the design requirement and the cooling effect, but there are also some need optimization of place, needs improvement, in order to achieve optimal cooling effect. Through the internal combustion engine cylinder head cooling channel 3d CFD simulation, got a lot of waterway flow field information for guiding the single cylinder head cooling channel development design and improve provide certain theoretical basis.
