Abstract: A virtual modal is developed by focusing on the type of JBP－63
electro-hydraulic control radial piston pump as to fit its working
conditions. The pump performance is predicted by using computer
simulation with static and dynamic characteristics. The modal results
are consistent with the experiment results. The numerical output showed
the system parameters changing process and the influence on the system
characteristics as adjusted the parameters. The results displayed that a
virtual modal according to the under designing system could predict its
performance and analysis by means of the modal, the application provided
very useful value and significance message for the design of system and
parameters optimization.
