摘要: 以FSAE方程式赛车CBR600发动机为研究对象,基于流体力学理论基础,通过分析发动机进气能量损失的原因与部位,初步设定进气系统相关结构参数;运用GT-Power软件创建赛车发动机二维模型,通过模拟分析,选定最佳进气总管长度为300 mm,稳压腔容积为3.5 L;用Catia软件对进气系统进行建模,通过Fluent软件对进气系统流场仿真,对比压力与流速云图,选择椭圆柱型稳压腔.路试结果表明,该进气系统能很好地满足CBR600发动机对进气的需要,中高速时充气效率提高5%~10%.Abstract: Taking FSAE formula racing CBR600 engine as the research objective and based on the theory of hydrodynamics,by analyzing the cause and location of the energy loss of the engine intake air,the relevant structural parameters of the intake system were initially set.The two-dimensional model of the racing engine was established by GT-Power software,simulation analysis was conducted to determine the optimum value of intake pipe length as 300 mm and the best regulator cavity volume as 3.5 L.The model of the air intake system was established by Catia.The Fluent software was used to simulate the flow field of the intake system and the elliptical cylider regulator cavity could be obtained by comparing the pressure and velocity diagrams.The experimental results showed that the air intake system could meet the needs of the CBR600 engine and improve the air intake performance by about 5% to 10%.
