本文通过对车用增压中冷柴油机中冷器设计要求的分析,提出了比传统的设计方法更为完善的中冷器优化设计方法:将设计问题构造成数学模型,采用优化计算方法,在电子计算机上进行中冷器设计。这样可以在满足中冷器设计要求的前提下,得到最小体积的最佳设计方案。本文以一台车用增压中冷柴油机的铝板翅式水-空中冷器为例,在PRIM250计算机上,利用CMIN16租序中的罚函数法进行计算,并把计算结果与原设计进行对比,证明优化设计方法要比传统设计方法的设计结果优越很多,而且花费的计算时间少。 Based on the analysis of the design requirements of intercooler for intercooler intercooler for vehicle, this paper presents a more perfect intercooler optimal design method than that of the traditional design method: the design problem is constructed into a mathematical model, and the optimal calculation method is adopted. Intercooler design on electronic computer. This can meet the design requirements of the intercooler under the premise of the smallest volume of the best design. In this paper, an aluminum plate-fin water-air coolers for a supercharged intercooled diesel engine is taken as an example. On the PRIM250 computer, the penalty function method in CMIN16 is used for the calculation. The calculated results are compared with the original design. Prove that the optimal design method is much superior to the traditional design method and takes less computational time.
