采煤机可靠性有限元分析

针对大同矿区的“煤层硬，顶板硬”，6m以上的特厚煤层储量丰富的特点，设计研制了大采高电牵引滚筒采煤机，为验证该采煤机的安全性和可靠性，采用虚拟样机技术对其关键零部件和整机进行三维建模，并对其进行有限元分析，分析结果表明该采煤机结构合理，工作稳定可靠，为大采高采煤机结构的设计提供了理论依据

Finite Element Analysis of the Reliability of Coal Winning Machine

In Datong coal mining hard coal, hard roof, the special thick coal seam which is 6 meters above is abundant, the company designs coal winning machine which is of large mining height, to test and verify the security and reliability of the shearer, its key parts and the whole machine is 3D modeling and finite element analyzecl, the results show that the structure of the coal winning machine is reasonable, stable and reliable, which provides theory basis for structure design of the Coal winning machine.
