Development of the Self-Propelled-Gun’s External Hydraulic Source

In this paper, according to the requirements of the self-propelled-gun’s hydraulic system test technology, using variable speed metering pump technology, a variable cain pressure predictive controller is developed. This method can improve response speed of pump-valve combined control. Then the self-propelled-gun’s external hydraulic source is developed, which can test a variety of self-propelled-gun equipment operation and its hydraulic system without starting the host. The trial operation proves: this test equipment is high common, high stability and high integration.
