液压集成块已广泛用于各种液压系统，然而要在集成块内正确地设计几十乃至上百个孔道，确定其内部孔道之间通与不通，仅靠手工校验还十分困难。本文提出了一个自动校验液压集成块内部孔道通断关系的算法，借助计算机，可以自动检查液压集成块内部孔道的状况。 Hydraulic manifolds have been widely used in a variety of hydraulic systems. However, it is still very difficult to properly design dozens or even hundreds of channels in the manifold to determine the intercommunication between the internal channels. This paper presents an algorithm that automatically verifies the on-off relationship between the internal channels of a hydraulic manifold. With the aid of a computer, the condition of the internal channels in the hydraulic manifold can be checked automatically.
