| Abstract: | Taking hydraulic support's liquid pipeline as the research object,a mathematical model was established for the support's hydraulic system including long pipeline,and the influence of pipe's length,diameter and modulus of volume elasticity on the post rising speed curve's response time and overshoots were investigated by analyzing the models using MATLAB/Simulink toolkit.The modeling and simulation methods can provide reference for the study of dynamic characteristics of other hydraulic systems. |
