摘　　要：介绍了低位放顶煤液压支架的架型。针对顶梁5种不同受力方式,利用ANSYS软件进行有限元分析,得出在不同工况下其最大应力和存在危险的部位。为该支架的设计改型提供了理论依据。The type of low top coal caving hydraulic support was introduced. A finite element analysis on the five different ways of stress with ANSYS software was carried out, and the maximum stress and the dangerous parts of roof timber under different conditions were figured out. The results will provide theoretical basis for the design and improvements of such hydraulic support.
