煤矿顶板的压力直接作用于顶梁上,因此顶梁性能决定着液压支架的支护性能。应用MSC.Patran/Nastran有限元软件的Design study模块对CYL9800型链接式超静定液压支架后顶梁进行优化设计,得到了合理的优化结果,为超静定液压支架的设计提供了一种较好的方法。
The pressure of the roof of the coal mine directly acts on the top beam, so the top beam performance determines the supporting performance of the hydraulic support. The Design study module of MSC.Patran / Nastran finite element software is used to optimize the design of the top beam of the CYL9800-type linkage-type statically indeterminate hydraulic support, and the reasonable optimization results are obtained. Good method.
