摘要：本文以某六缸柴油机性能开发为例，介绍了该发动机在选型及最终的性能标定中应用DOE试验设计方法完成该机型的开发。在选型过程中，应用先进的DOE理论，通过利用最少的试验资源确定满足目标要求的最终方案，确定最终方案后应用自动标定软件，采用软件自带的试验设计程序、建模算法及优化程序等进行数据分析及建模优化计算，获得满足排放目标前提下的最佳经济性。结果表明，应用DOE理论，能够运用较少的试验次数确定最佳的组合方案。利用商业的自动标定软件Cameo设计全局工况的DOE点，建立整个发动机的全局的模型，完成该发动机的性能标定。与常规的选型及性能标定对比，高效准确，节省大量的试验资源，获得更好的效果。

Abstract：Taking a six-cylinder diesel engine performance development as a example, introduced the hardware selection and performance calibration used the DOE experimental design method to complete the development of the engine .In the process of selection, adopted advanced DOE theory, through using the least testing resources to determine the final plan. At last, using the software that comes with the test design process, software modeling algorithm and optimization procedure for the data analysis and modeling calculation, obtain the best economic under the target of emission. The results show that the application DOE
theory can use less number of trials to determine the best scheme. Using software Cameo , design the DOE
point, to establish a global model of the engine, complete the performance of the engine calibration. Comparing with the normal calibration, efficiently and accurately, saving a lot of trial resources to get better results.
