摘　　要：球磨机是粉磨作业所需的重要设备,为了提高生产效率,延长提升条的使用寿命,需要选择合适的耐磨材料以及设计出合理的耐磨结构。根据两种生物耐磨特征,运用三维建模软件建立了光滑、横向条纹、纵向条纹、凸包的仿生结构特征提升条的球磨机模型。通过数值模拟与磨矿试验,统计了磨矿过程中4种不同表面特征提升条的应力分布、累积力、微观磨损形貌等信息。结果表明,具有仿生结构的提升条能够有效缓释提升条在磨矿时的等效应力,降低提升条的磨损消耗,横向条纹仿生结构在4种提升条中的耐磨性和磨矿效果最佳。The ball mill is an important equipment required for the grinding operation.In order to improve the production efficiency and prolong the service life of the lifting bar,it is necessary to select suitable wear-resistant materials and design a reasonable wear-resistant structure.Based on two kinds of bio-abrasion characteristics,the3 Dmodeling software is used to establish a ball mill model with smooth,horizontal stripes,vertical stripes,and convex hull bionic structural features.Through the numerical simulation and grinding experiments,the stress distribution,cumulative force,and microscopic wear morphology of four different surface features in the grinding process were statistically analyzed.The results show that the lifting strip with bionic structure can effectively release the equivalent stress of the lifting strip during grinding,reduce the wear,and tear consumption of the lifting strip.It is found that the horizontal stripe bionic structure has the best wear resistance and grinding effect in the four lifting strips.
