頂置凸輪式汽油機配氣機構(gòu)設(shè)計研究
摘要：以發(fā)動機的配氣機構(gòu)做為研究對象，并搭建頂置凸輪式汽油機配氣機構(gòu)模型，并對其進行優(yōu)化。運用CATIA等軟件對其進行了計算及應(yīng)力分析，得到凸輪型線等一系列數(shù)據(jù)。
氣門凸輪型線是氣門機構(gòu)的核心，氣體凸輪型線是優(yōu)化氣體分布設(shè)計的重要途徑。結(jié)論證明：優(yōu)質(zhì)的凸輪型線可以提高凸輪型線的性能。
關(guān)鍵詞：配氣機構(gòu)；凸輪型線；優(yōu)化設(shè)計
Design and study of overhead CAM type gasoline engine
Abstract：As a research object, the engine's gas distribution mechanism is set up, and the model of the gas-engine distribution system is set up and optimized. Using software such as CATIA to calculate and stress analysis, award for a series of data such as CAM line.
The valve CAM line is the core of the valve mechanism, and the gas CAM line is an important way to optimize the distribution of gas. Conclusion: high quality CAM line can improve the performance of CAM line.
Key words: match air mechanism；CAM line；optimized design
