容积式机器的概念创新设计方法研究

Methods of innovative concept design for volumetric machine

从三种容积式机器实例出发 ,分析了此类机械中空间密闭容腔的一般组成原理和形成容积变化的顶层方法 .采用图模型对若干典型容积式机器的空间密闭容腔组成和容积变化机理进行了抽象描述 ,包括容腔构件的运动方式特征、自由度以及构件之间的共轭运动副特征 ,并从中归纳出可行的创新途径 .

Based on three instances of volumetric machine, this analyzed the general formation theory of sealed space and the super methods for changing its volume. The sealed space of several typical volumetric machines through graph model, including the components surrounding the sealed space and their kinematic characters, degree of freedom (DOF) and kinematic pairs between them was abstractly illustrated. Proper methods of innovative design were proposed, and a simple innovative designing instance was given to test the efficiency of innovation design theory.
