Research of Virtual Experiment Hydraulic Pressure Component

The effect of virtual experiment in teaching and experiment of the principle of hydraulic pressure was discussed,the(idea) and method in design of virtual instrument and experiment of hydraulic pressure element was introduced.Virtual experiment can(directly) explain the structure,principle and working characteristic of hydraulic pressure element.An experiment about the property curve in unlock process of lead-first overflow valve was done based on the Labview 7.1,which is similar with the real instrument(interface) and processes the guidance significance for the design of virtual experiment software.
