摘　　要：为研究普通合金9Mn2V和钨基粉末硬质合金两种材料磨杆的动静态特性,对其性能进行评价,基于有限元仿真对两种材料磨杆进行了动静态性能研究,并与模态试验结果进行了对比分析;两种材料磨杆理论分析值与试验数据间的误差在8%以内,证明了所建立有限元模型很好的反映了实际结构以及仿真所得结论:钨基合金磨杆比9Mn2V磨杆具有更好的静刚度和动态性能,即钨基硬质合金能够显著提高磨杆性能的有效性。In order to research the static and dynamic performances of two kinds of materials,9Mn2V and tungsten-base alloy grinding rods, and evaluate their performance, static and dynamic performances study of them is made based on ANSYS, and mode test is also be made. The errors between theoretical analysis and test value are all within 8% of two kinds of materials grinding rods. It proves that the established finite element model reflects the actual structure very well and the conclusion of the simulation is effective that tungsten-base alloy grinding rod t has better static and dynamic performance than 9Mn2V grinding rod.
