摘要
利用有限元分析软件ANSYS对煤矿破碎机关键部件锤头进行单体静力分析,得到了使用不同材料锤头的应力、应变分布规律。为煤矿破碎机的锤头设计、选材提供了理论依据。分析结果显示:应力及应变在锤头作用面上分布不均匀,最大应力发生在销轴与销轴孔接触的上边缘处,3种材料均满足安全要求,高锰钢锤头抵抗变形的能力更强,安全系数更高。
Using finite element analysis software-ANSYS to crusher key components hammer head for single static analysis, the siress and： strain distribution rule of the hammer head are obtained for different materials. Provide a theoretical basis for coal ]nine crusher of hammer head design, selecting material. Analysis results show that： stress and strain in the hammer head role uneven distribution of surface, the maximum stress occurs in the pin shaft and pin axle hole on the contact edge, three kinds of materials can meet the safety requirements, ZGMnl3 hammer head resist deformation ability stron_ger,_ and safety coefficient is higher.
