摘　　要：建立了液压约束活塞发动机配流系统的多目标优化模型,采用复合形法进行了优化研究。通过MATLAB语言程序对配流系统进行优化设计,并对优化数学模型进行求解。通过对优化前后的结果进行分析,证明了液压约束活塞发动机配流系统多目标优化模型的正确性。对配流系统优化后的容积效率进行了仿真分析,仿真结果与实验结果对比表明,容积效率的改善程度比较显著。A multi--objective optimization model of valve type orifice system of hydraulic confined piston engine was built. The optimization study was done by complex method. The optimization design was done by MATLAB language and the optimization mathematic model was resolved. The results of re--optimization and pre--optimization are analyzed, which proves that the optimization model of the valve type orifice system of HCPE is correct. Volumetric efficiency of pre--optimization is simulated. Contrasted with the experimental results, the increase of volumetric efficiency is great and about 10 %.
