摘要
本文利用CATIA软件建立WD615.67A柴油机的气道-气门-气缸的三维几何模型,然后采用PRO-SURF、PRO-AM对几何模型重建表面及划分网格。应用所建立的模型研究在发动机不同气门升程时,对缸内流场的影响。
In this article, the CATIA is used to build the intake passage - valve - cylinder three - dimensional model of the WD615.67A diesel engine. Mterwards, reconstructs surface and meshes grid to the model using the PRO - SURF and PRO - AM. Analysis is done for the influence of flow field in different valve lift using the new model.
