一、概述随着电子技术的迅速发展,电子数字控制已经得到应用。而做为开关线路设计方法——逻辑推算方法,也被其他技术领域所引用,液压回路也属于开关线路,引用逻辑推算进行液压系统设计,将是完全可能的。逻辑代数是逻辑推算的工具,它适用于对复杂的开关线路分析、综合及简化工作,逻辑代数又是描述具有两种稳定状态元件的工作情况的方法。逻辑代数和普通代数不同,逻辑代数的变量只允许取两个不同的值即“0”和“1”, I. Overview With the rapid development of electronic technology, electronic digital control has been applied. And as a switch circuit design method - logic calculation method, has also been cited in other areas of technology, hydraulic circuit also belongs to the switching circuit, reference logic calculations for hydraulic system design, it is entirely possible. Logic algebra is a logical deduction tool, it is suitable for complex switching circuit analysis, synthesis and simplification, and logic algebra is a description of the work with two steady state components of the method. Logical algebra and ordinary algebra are different, logical algebra variables allow only two different values ​​?? to take “0” and “1”
