【Abstract】 Based on the determination of the three-dimensional cavity design scheme of the plastic intake manifold in automobile engine, this paper carries out the structural design, welding design and the CAE analysis of the plastic intake manifold. The calculation results show that the intake manifold can meet the strength requirements in terms of burst pressure and vibration stress, and the designed intake manifold meets the original design goals.更多还原
