| 摘 要： | 将正交设计用于增压柴油机的模拟计算,为柴油机的性能预测和优化开辟一条新的捷径。为了既不漏掉某些重要因素和有利水平的影响,又能迅速找出最佳方案,进行了三重正交表计算。同时并考察了各因素对柴油机性能的影响规律,以及各因素之间的交互作用。此外,还以四种喷油压力调整试验所对应的四个燃烧持续期为水平,进行了局部调整参数的模拟计算。通过比较,计算值与实测值基本吻合,证明了正交设计模拟计算得出的结论具有实际意义,正交设计应用于模拟计算是寻求最佳方案的可行办法和捷径。

| Abstract: | By using orthogonal design to simulation of a turbocharged diesel engine,investigates a short-cut method for prediction and optimization of its performance.The calculation with threefold arraies can obtain a optimum scheme quickly and prevent that some important factors and beneficial levels are possibly omitted.Influences of every factor on the performance and mutual effect of the factors arc analyzed.Four combustion durations corresponded with the tests of fuel injection pressure adjustment are used as the 4 levels in simulative calculation.Result shows that the calculation agrees with the tests, and so this method is feasible. |
