Controlling and simulation system for hydraulic valve testing based on Qt

Abstract

Hydraulic valve is not only an important part in construction machinery but also widely used in modern industry area. In Hydraulic valve’s research and design process, it needs large amount of testing experiments to verify the accuracy of design. The design in this paper is a real-time controlling and simulation system for hydraulic valve testing experiments based on Qt platform. In this design, the controlling parameters would be preset. Then the stimulation waves and testing data are plotted and outputted based on the feedback information from lower position machine. This system creates the sub-tasks unites and different classes based on the requirement of testing experiment, followed by plotting the software interface with OpenGL.
