摘  要:
利用三维CFD软件AVL.Fire对某重型柴油机冷却水套进行分析,本分析主要是在概念设计方案的基础上进行的数值计算。基于仿真结果分析初期设计方案的不足,并寻找解决方法。在寻找解决方案的过程中兼顾了零部件制造的各项工艺指标,并保证改进的设计方案不仅能够满足发动机冷却性能的要求,还能降低零部件生产过程中的废品率,提高经济效益。

摘  要:
This paper utilizes AVL.Fire software to analyze the cooling water jacket of a heavy duty diesel engine.This analysis is mainly numerical calculation based on the concept design.Based on the simulation result,the shortage of the early design is found out and a solution is given.The each technical index of component manufacture is considered in the process of finding the solution.The improved design plan not only can meet the demand of engine cooling performance,but also can reduce the reject rate in productive process,and improve the economic benefit.
