遗传算法在柴油机喷油系统参数优化设计中的应用研究

为了获得理想的燃油喷雾特性，需要对柴油机喷油系统参数进行优化设计，但由于所涉及的设计参数多、设计目标多，采用传统的优化设计方法，难以获得令人满意的结果。本文应用遗传算法，根据柴油机燃油喷雾特性的计算公式和6V150柴油机的具体情况，对其喷油系统的参数进行了优化设计；对基于遗传算法的参数优化过程进行了全面、简要的介绍。结果表明：遗传算法可适用于多设计变量、多设计目标的柴油机喷油系统参数优化设计。

A STUDY ON THE APPLICATION OF GENETIC ALGORITHM TO THE PARAMETER OPTIMIZATION DESIGN FOR FUEL INJECTION SYSTEM OF DIESEL ENGINES

In order to obtain the ideal fuel spray characteristics, it is necessary to optimize the design parameters of the fuel injection system in diesel engines. In the paper, on the basis of the equations of fuel spray characteristics, genetic algorithm (GA) was applied to optimize the parameter of the fuel injection system for 6V150 diesel engines. The process of the parameter optimization design based on GA was introduced and briefly discussed in many of its respects. The results show that GA is suitable for the parameter optimization design for fuel injection systems of diesel engines.
