基于Ansys的SL750采煤机机身强度分析

SL750 Shearer Body Strength Calculation Based on Ansys

以SL750采煤机为研究对象,针对其机身结构载荷分布情况,建立SL750采煤机机身受力模型,通过Ansys有限元方法计算采煤机机身变形量及应力分布情况,拟合采煤机工作状态下机身变形量曲线及等效应力分布云图,对比分析机身组成结构及工况下应力及应变分布,分析数据显示:SL750采煤机机身结构设计合理,工况下具有较好的刚度和强度,最大变形量约为2.21 mm,出现在牵引部泵站腔体侧壁;最大应力约为208 MPa,出现在前牵引部联接支撑腿的根部。此计算结果对于国内中厚煤层大功率采煤机研发具有一定的参考价值。

Eickhoff SL750 shearer as the research object, load distribution for the fuselage structure, model SL750 shearer body by force, shearer body deformation and stress distribution calculated by the finite element method, the proposedaggregate amount of fuselage deformation curve and stress contours the shearer work state, comparative analysis of body composition structure and operating conditions of stress and strain distribution, analysis of data shows： Eickhoff SL750 shearer fuselage structural design is reasonable condition has good stiffness and strength, the maximum deformation is about 2.21 mm, appear in the side walls of the cavity of the traction portion pumping station; maximum stress of about 208 MPa, roots appear in the first coupling the supporting leg of the traction portion. The result of this calculation SL750 shearer localization has certain reference value.
