发动机气门弹簧的模糊优化设计

The Fuzzy Optimal Design of Valve Spring of Engine

近代摩托车用汽油机普遍采用顶置凸轮轴结构（OHC）和组合式气门弹簧。

The overhead camshaft ( OHC ) and combination valve spring structure are in common use in modern motorcycle gasoline engine .

它主要被用于XXX系统的复进簧或者航空发动机的气门弹簧等特殊场合，而在民品中应用比较少见，这是由于多股簧制造工艺复杂、制造成本较高。

It is mainly used in recoil check spring of XXX system , complex aero-engine valve spring and so on . However , their application for civilian use is relatively rare as a result of their complex manufacturing process and high manufacturing cost .
