Analysis of Dynamic Characteristics of Hydraulic Control System of Hydraulic Support
In order to realise the hydraulic system of the hydraulic support and improve the efficiency of the hydraulic control system,AMESim simulation software is applied to analyse the dynamic characteristics of the stand column.The application of AMESim simulation software to analyse the dynamic characteristics of the hydraulic control system of the stent column,increase the flow rate of the pump station can obviously improve the speed of the column lift,and have a small impact on the speed of the column lowering;shorten the displacement of the telescopic bar to shorten the time of the column lifting and lowering;increase the diameter of the hydraulic check valve and the diameter of the hydraulic supply pipeline to improve the speed of the column lifting and lowering,and the optimal combination of the parameters of the hydraulic control system,the time of the column lifting was 3.5 s,which was improved by 17％;column lowering Under the optimal combination of hydraulic control system parameters,the column lifting time is 3.5 s,which is about 17％higher;the column lowering time is 2.1 s,which is about 16％higher,and the efficiency of the column control system of hydraulic support is improved.
