Study on The system Characteristic of a Crane walking Hydraulic System Based on AMESim

摘要

A system simulation model is established by multidisciplinary simulation software Amesim.This model is on account of travel system of a certain hydraulic crawler crane,mainly on selector valve and load sensing pump.Based on this model simulation and dynamic analysis is carried out,then output volume change characteristics of load sensing pump along with load changes is got.Contrasting the simulation result and experiment result,correspondence is very good,which indicate that this model and related parameters are in accordance with real system.A simulation analysis method used to analysis changes of load sensing pump along with load changes is provided.
