| 摘 要： | 基于多学科设计优化方法,以某型高压共轨柴油机匹配的共轨管容积最佳、压力波动最小、质量最小和进油口位置最佳为目标函数建立共轨管多学科设计优化体系,并在充分考虑各学科间耦合作用的基础上,采用模拟退火算法对多学科设计优化模型进行优化求解。研究结果表明:共轨管的容积由原设计值21.991 cm3减少到21.756 cm3,减小了1.07%;总质量由1.250 kg减少到1.165 kg,减小了6.8%;压力波动幅度由6 MPa降低至5 MPa,降幅为16.7%;优化后共轨管的整体性能得到提高,能够满足高压共轨燃油喷射系统的要求。 |

| Abstract: | Based on multidisciplinary design optimization(MDO) method,the rail tube MDO system was established using the optimal volume,least pressure oscillation,the smallest mass and the best inlet position as the objective functions.Taking the multidisciplinary coupling effect into full consideration,the MDO system was solved by the simulated annealing algorithm.The results show that the rail volume is decreased from 21.991 cm3 to 21.756 cm3,with 1.07% reduction ratio;the mass of rail tube is reduced from 1.250 kg ... |
| Keywords: | high pressure common rail diesel engine rail tube multidisciplinary design optimization |
