ABSTRACT
Automobile engine belongs to the core components of automobile , however, the intake manifold belongs to the major part of engine, it can affect the automobile performance parameters such as the power, fuel consumption, torque and so on. Therefore, the intake manifold performance quality is good or bad,it relates directly to the engine and vehicle performance, and because of that improving the quality of the intake manifold has a positive meaning to the engine and automobile performance parameters. This article studied the intake manifold design modeling and fixture design, its purpose is mainly based on process analysis, Process planning design ,process route planning,fixture design,autocad, proe and so on using and mastering, and use the mechanics of materials, metal cutting discipline knowledge designed the intake manifold fixture, and use proe establishing intake manifold and fixture 3d model, autocad software drawing assembling drawings and parts drawings, etc. First, this article will outline the intake manifold current situation and trend of development , introduces the latest development. Secondly, the modeling of the intake manifold of purpose and meaning makes some brief elaboration. Again, for the intake manifold processes of processing do a detailed design and calculation. Finally, this article describes the intake manifold fixture design process.
