Study of modulation simulation of hydraulic system based on virtual technology

The simulation of hydraulic system has lagged behind in the machinery and the electrical system. The fast development of computer technology and the virtual instrument technology＇s has provided the technical support to the modular construction virtual hydraulic system. With the present virtual instrument in figures and diagrams programming software, various hydraulic element＇s simulation model, the part coupling module, and the virtual hydraulic system simulation models with the virtual element simulation model can be set up. The hypothesized instrument can connect the real equipment with the virtual simulation model, move the time parameter real-time input simulation model the equipment, realize the systems operation monitor and the failure prediction. This technology has developed the hydraulic instrument＇s concept, realized the actual situation union truly, and virtual instrument development for virtual instrument simulation system.
