Abstract :
This article has proposed a new method for designing and studying engine intake system based on the technology of CAD/CAE/CFD integration. Firstly, according to the similarity principle and pressure wave theory, the structure parameters of target engine intake system were defined referencing the similar engine. Then, the intake system parameters were input into GT-power, and the intake system performance was simulated and optimized. Next, the 3-D structure model was designed based on CAD software and optimized values. After that, the key parts of intake system were analyzed and optimized by using CAE and CFD. As a result, a new intake system has been designed. The whole processes of designing and studying intake system included parameters define, performance optimization, structure design, flow calculation, noise and vibration analysis, were coupled together. And the feasibility and effectiveness of the idea was validated through practical example. The study results have provided guidance for designing intake system of engine.
