摘　　要：为了提高增压压力峰值而又抑制增压器的燃油泄漏率,对影响超高压共轨系统燃油增压器性能的控制室进油孔直径和增压室容积等多个结构参数的灵敏度进行了优化。利用AMESim软件建立了超高压共轨系统仿真模型,并根据超高压共轨试验系统对仿真模型进行标定。利用ISIGHT软件的优化功能,选择了NSGA-Ⅱ、NCGA和AMGA等3种算法对增压器进行优化计算,结果表明:经优化后,燃油增压器的增压能力和经济性均显著提升。其中,AMGA算法优化效果最佳,增压压力峰值提升了19.1%,燃油泄油率降低了7.72%。In order to improve the boost pressure peak while suppressing the fuel leakage rate of the supercharger,the sensitivity analysis and optimization of the structural parameters of the fuel supercharger of the ultra-high pressure common rail system were carried out.A simulation model of the ultra-high pressure common rail system was established using AMESim software,and the simulation model was calibrated through the ultra-high pressure common rail test system.The DOE module of ISIGHT software was used to analyze the sensitivity of multiple structural parameters such as the diameter of the oil inlet hole in the control room and the volume of the booster chamber that affect the performance of the fuel booster.Using the optimization function of ISIGHT software,three algorithms such as NSGA-Ⅱ,NCGA and AMGA were selected to optimize the supercharger.The results show that after optimization,the supercharging capacity and economy of the fuel supercharger have been significantly improved.Among them,the AMGA algorithm has the best optimization effect.After the algorithm is optimized,the peak boost pressure has increased by 19.1%and the fuel drain rate has been reduced by 7.72%.
