Analyses of Influential Factors of Dynamic Characteristics of Hydraulic Pump Test System

Abstract

A set of hydraulic pump test system was designed according to national test standard. The simulation model of the test system was built in hydraulic simulation software AMESim. Through setting and adjusting simulation parameters, groups of simulation results were obtained and graphed with different pipeline diameter, pipeline length, elastic modulus of pipeline material, oil temperature and oil bulk modulus. The description about the influences of the above factors on system dynamic characteristics and the analyses about the reasons were given. The advices on optimizing design of hydraulic test system were presented contraposing different parameters and design requirement.
