发动机铝合金陶瓷镶块摇臂是一种材料组合型技术创新产品，用它替代传统的锻钢摇 臂可明显改善发动机配气机构的耐磨性和动特性，减少对发动机的维修。在分析铝合金陶瓷镶块摇臂批量生产 中的关键制造技术的基础上，提出了其研制过程的一般模式，论述了现代设计理论和方法在其设计过程中的应 用，最后阐明了其制造工艺上的几个创新点和创新方法。这些内容对于今后发动机重要结构件的研制开发工作 具有指导意义。

： As a combination of two materials with different properties, the aluminum die-cast rocker arm with a ceramic insert for internal combustion engines is a kind of technical improved new product. Replacing the conventional forged steel rocker arm with it can ameliorate the wear resistance and dynamic characteristics of the valve trains greatly, and reduce the maintenance of engines evidently. On the foundation of analyses of the key manufacturing techniques suited to mass production of the aluminum die-cast rocker arm with a ceramic insert, a general model of developing procedure of it is put forward. At the same time, the applying methods of modern devising theories and means to the design process of this type of rocker arm are expounded, and several innovating points and ways of producing technologies of it are described as well. The contents of this thesis have guiding significance to the development of the important structural parts of internal combustion engines.
