液压支架偏心载荷工况下的承载性能分析

Analysis of Load-bearing Performance of Hydraulic Support under Eccentric Load Conditions

由于煤矿开采过程中,在偏心载荷工况下的承载最为恶劣,对液压支架的承载具有较高的要求。采用有限元仿真分析的形式,对液压支架在偏心载荷工况下的承载性能进行分析,结果表明:液压支架受到的应力满足使用的需求,顶梁结构受到的应力梯度较大,需进行一定的结构优化,保证液压支架的长期稳定使用。

As the load bearing in the eccentric load condition is the most severe in the coal mining process,the load bearing of the hydraulic bracket has high requirements.The bearing performance of hydraulic bracket under eccentric load condition is analyzed in the form of finite element simulation analysis,and the results show that:the stress on the hydraulic bracket meets the prelude of use,the stress gradient on the top beam structure is large,and certain structural optimization is needed to ensure the long-term stable use of the hydraulic bracket.
