Abstract

散体物料在装卸过程中装载机铲斗结构设计的不合理是产生磨损的主要原因，故设计合理的系统结构是解决装载机铲斗磨损的主要办法。本研究以砂石物料作为试验对象，建立了装载机铲斗的离散元仿真模型。通过仿真分析确定了一次铲装法为装载机铲斗的铲装轨迹，并分析预测出主刃板为主要的磨损部件。在此基础上，分析耐磨材料对主刃板磨损量的影响，然后对主刃板结构进行改进，通过改进前后主刃板的磨损和受力情况进行对比。其仿真结果表明：当耐磨材料的磨损常数越小和维氏硬度越大，各个耐磨材料的Archard Wear模型和Oka Wear模型的磨损深度越小，耐磨材料的耐磨性越高，并确定方案3为最佳的主刃板结构参数。改进后主刃板结构的磨损和受力情况都得了改善，并验证了主刃板结构改进的可行性。
