摘　　要：在露天煤矿中,煤矿装载机主要的作业流程是将爆破后的松散煤矿铲装到卡车上,再由卡车将煤运输出工地。针对煤矿企业提出的煤矿装载机铲斗容量与运输卡车容量不匹配导致装卸效率低、铲斗磨损严重等问题,基于四个基本参数法对某5吨煤矿装载机铲斗进行参数设计,结合装载机作业工况及露天煤矿物料特点,进而确定煤矿铲斗的几何形状,再通过UG建立与实际尺寸相同的三维模型。在三种典型的载荷工况下,使用Workbench对模型进行静力学分析,得到铲斗的应力与位移分布,分析的结果均满足材料的许用范围,故该分析结果可作为装载机铲斗设计和优化的依据,对相似作业流程及物料特点的工程机械和结构的改进与计算有一定的工程指导意义。In open-pit coal mine,the main operation process of the coal loader is to shovel the loose coal into the truck,and then the truck will transport the coal to the site.Aiming at the problem that the coal loader bucket capacity and the transport truck capacity does not match(which results in low efficiency of loading/unloading,and severe wear of the bucket),based on the four-basic-parameter method,the bucket of a certain five-ton coal loader is designed.Based on the operating conditions of the coal loader and the material characteristics of the open-pit coal mine,the geometric shape of the bucket is determined.UG is used to build a 3D model,and Workbench is used to statically analyze the model under three typical load conditions.The stress and displacement distributions of the bucket are obtained.The analysis results all meet the allowable range of the material,so the analysis results can be used as the basis for the design and optimization of the loader bucket.This study has certain guiding significance for the improvement and calculation of machinery and structure with similar operation flow and material characteristics.
