电控柴油机标定中空间填充试验设计的应用研究

Application Research on Space-filling Experiments Design in Calibration of Diesel Engine

本文通过空间填充试验设计得到75个工况点,然后在一款电控高压共轨柴油机仿真模型上进行虚拟试验,得到发动机控制参数输入和性能输出的数据库,基于输入输出性能数据库建立的响应模型,经验证具有很好的预测精度且满足建模要求。

In this paper, the proper experiment point was selected through space-filling experiments designs,and then the simulation model of high pressure common rail diesel was operated according to these points,which results engine performance database. The response model based on the input-output performance of the database has a good prediction accuracy to meet modeling requirements.
