针对工程中两液压缸的高精度同步问题,本设计采用一种新型的功能材料,即大磁致伸缩材料,作为阀的电 机转换元件,并采用8051单片机采集与处理两液压缸的位移反馈信号,从而达到高精度同步控制.阀的特性分析结果显示其能够实现两液压缸的高精度同步控制,并具有一定的抗干扰能力. Aiming at the problem of high-precision synchronization of two hydraulic cylinders in the project, the design uses a new type of functional material, namely a giant magnetostrictive material, as a motor conversion element of a valve, and adopts a 8051 single-chip microcomputer to collect and process the displacement feedback signals of the two hydraulic cylinders , So as to achieve high-precision synchronous control.The valve characteristics analysis results show that it can achieve high-precision two-cylinder synchronous control, and has a certain anti-interference ability.
