高效深栽牵引式植树机钻螺旋翼片的有限元分析

目的]分析深栽钻孔机钻螺旋翼片受力的变形和应力情况。方法]应用有限元分析软件ANSYS,按照高效深栽植树机钻头的结构尺寸和实际工作条件,建立钻螺旋翼片的三维实体模型和有限元模型,进行了静力分析。通过对植树机钻升土理论的分析与计算,确定了翼片最优导程和工作受力参数,并在ANSYS中直接建立三维实体模型,螺旋翼片的有限元模型并进行静力分析。同时,对翼片螺旋角α与其应力值之间的关系进行了探讨。结果]通过对钻的静态分析,得到了主轴工作时的应力和变形数据。分析数据表明俞国胜老师研制的深栽钻头静强度可以满足工作要求,且结构参数存在一定富余,可以实现进一步的结构优化。结论]该研究为螺旋翼片进一步的结构优化设计提供了理论依据。
