摘  要:
为设计FSAE赛车进气效果最佳的谐振腔,本文通过GT-Power软件,模拟分析得到某款单缸发动机在高转速工况下最佳谐振腔直径,根据分析结果选取谐振腔进出口锥角,利用ANSYS中的FLUENT模块对谐振腔进行参数优化对比分析,得到谐振腔的流场分布图。结果对比表明,高转速工况时选取直径为120 mm的谐振腔,进口直径为50 mm,出口直径为62 mm,进出口锥角分别为60°、30°的谐振腔进气气流供应稳定,进气效果最佳。该分析改善了FSAE赛车谐振腔对发动机进气性能的影响。

摘  要:
For best design air intake cavity of FSAE car, based on the GT- Power software, optimal cavity diameter of a single cylinder engine under the condition of high-speed rotation is obtained by simulation analysis. Import and export cone angle of cavity is selected according to the results of the analysis. Using ANSYS FLUENT software modules for the resonator parameters optimization analysis, the cavity flow field distribution is got. The results of comparison show that under high-speed working condition, when selecting a cavity of diameter of 120 mm, with import diameter of 50 mm, export diameter of 62 mm,taper angle of import and export respectively as 60 ° and 30 °, the air supply of cavity inlet is stable, intake works best. The analysis has improved the FSAE car cavity effect on the performance of engine air intake.
