Computer simulation and model test research on strength test of hydraulic support

Abstract

This paper took ZT6500/19.5/34 hydraulic support as an example, made a solid model construction on its prototype and 1 to 5 model by SolidWorks software, proceeded a computer simulation analysis on simplified support prototype and its model with the status of concentration load on central section of support top beam by ANSYS software, drew relevant total displacement figure and equivalent stress figure, found out relevant distribution rule. Based on the similarity theory, static similarity rule and static similarity condition of hydraulic support model test were constructed, hydraulic support model test board and its hydraulic control system, data collecting and processing system were constructed. According to the national standard, strength test was made on support model with the status of concentration load on central section of support top beam. The research shows that computer simulation results are consistent with actual model test results, which verifies the accuracy of computer simulation results. The method of combining computer simulation test with hydraulic support model test has the advantage of less test cost, short exploitation period, accurate and comprehensive analysis, which enhances the level of entire design, calculation and test and provides an effective way of systematically theoretical and experimental study on hydraulic support.
