Abstract:This paper presents a new method to describe the selection design of directional control valves in the form of matrix. The directional control valves in hybrid are the basic units to implement the distribution of flow in the hydraulic system. Both the design requirements of the hybrid hydraulic system and the basic units are expressed by the adjacency matrices. Therefore, the selection design of directional control valves is the process to decompose the adjacency matrix of the system into a series of sub-matrices according to the decomposition rules. The defined rules of adjacency matrices are obtained according with the composite physical model of several valves. For obtaining easily the selection design of directional control valves, the library of basic units is established. The style of directional control valves is obtained by matching the sub-matrices with the matrices of basic units. Through configuring the others components, a thorough conceptual design process of the hydraulic system is established. Example is given to illustrate the whole design process in detail.
