The Modal Optimization of Plastic Intake Manifold for Gasoline Engine

摘要：

　　Based on the problems of low-modal leading to resonance and fatigue failure caused therein,the first-order modal fre-quency of the plastic intake manifold was analyzed in this paper.By optimization the structure of the intake manifold and the support bracket,the target mode of the intake manifold was achieved under the principles of lightweight and low cost.Meanwhile,based on many times of optimization design,the methods and approaches for modal optimization of intake manifold were summarized in this paper.
