基于ANSYS有限元对液压支架前连杆的数值模拟

Finite Element Numerical Simulation for Hydraulic Support Front Track Rod Based on ANSYS

利用三维绘图软件Pro/E建立大采高液压支架前连杆的实体模型,根据大采高液压支架受力分析图对前连杆受力情况进行计算。利用ANSYS有限元分析软件的结构静力学分析模块和模态分析模块,对前连杆进行静力分析和模态分析,然后根据淮北矿业集团许疃矿7229工作面ZY11000/28/63型大采高液压支架受顶板周期来压的实际情况,结合ANSYS数值模拟的结果综合分析前连杆的受力情况和抗屈服能力,这对大采高液压支架的安全性以及机械化综采有着实际的指导意义。

3D drawing software Pro/E big mining height are used to broken hydraulic support before connecting rod entity mod-el it set up, According to the big mining height are broken hydraulic support force analysis of connecting rod bearing before. Using the ANSYS finite element analysis software structure statics analysis and modal analysis module, Static analysis and mo-dal analysis was carried out on the first connecting rod, Then according to the Huaibei Mining Group, Xutuan Mine 7229 working plane ZYl1000/28/63 type of large mining height are broken hydraulic support by the actual situation of periodic roof pressure, Comprehensive analysis combined with the result of ANSYS numerical simulation before the force of the connecting rod and the ability to resist yield. The big mining height are broken and the safety of hydraulic support has practical guiding signi-ficance to the mechanized mining.
