依据有关液压支架的试验标准,选取了ZY6400/21/45型掩护式液压支架进行计算机模拟仿真,得出其应力和变形分布,为ZY6400/21/45型掩护式液压支架的设计提供了理论依据。
Based on the test standard of hydraulic support, the ZY6400 / 21/45 type shield type hydraulic support was selected for computer simulation and the stress and deformation distribution was obtained, which provided a theoretical basis for the design of ZY6400 / 21/45 type shield hydraulic support .
