| With the continuous development of coal industry, high yield and high efficiencycompound mining equipment progress quickly. As the main compound mining equipment,hydraulic support puts forward higher requirement for its performance. If we make variousperformance tests with the traditional design method, cycle is long, the cost is high, changingparameters or conditions is very difficult. Sometimes, it even can not be achieved. This articlebased on one type of hydraulic support’s hydraulic system, studies some of the dynamiccharacteristics of hydraulic support, and has calculated the pressure loss of liquid.This thesis models the hydraulic system of hydraulic support, using the software ofAMESim. This thesis’ auxiliary tool is Visual Basic, using it we make theman-machine interface of hydraulic support’s hydraulic system, and write the interfaceprogram of Visual Basic and AMESim, in the last, realizes the joint simulation of Visual Basicand AMESim.Based on the hydraulic support’s hydraulic system establishment of hydraulic model, wemake the simulation, and study the dynamic characteristic of Emulsion pump, pillarcontrolcircuit and goes control circuits, which are the main loops. in addition, using the way ofdamping hole in instead of hydraulic support directional control valve in hydraulic system, thesystem model is simplified. And then analysis the Simulation, using the simulation results, we calculate the pressure loss of hydraulic support’s hydraulic system.This article makes the aim of controlling hydraulic support’s hydraulic system by theway of making machine interface control, and makes the operation more convenient. Weanalysis the simulation system through the way of changing parameters, get the main factorsof influence hydraulic support’s hydraulic system dynamic. It provides theory basis for newhydraulic support’s research and design, improving hydraulic support’s performance. |
