摘要

传统铲斗强度分析是将铲斗受力简化为集中力或均布力,这样简化将导致铲斗强度分析结果不精确。以Sandvik 1400e铲运机为例,通过Hyper Mesh对铲斗进行前处理,应用EDEM仿真铲运机工作过程,得知铲斗在工作过程中受载具有复杂多变的特点。通过离散元与有限元耦合的方法,对铲斗进行了精确加载,完成铲斗在载荷工况下的强度分析与磨损量计算,为铲斗结构优化提供理论依据。

Abstract

Bucket force is simplified as concentrated force or uniform force in traditional bucket strength analysis,which will result in inaccurate bucket strength analysis result. Taking Sandvik 1400 e scraper as an example in this paper,carrying out pretreatment on the bucket based on Hyper Mesh,simulating scraper working process by EDEM,it is obtained that bucket is characterized by complication and variable load during scraper operation. By way of coupling discrete element and finite element,bucket was loaded precisely,then bucket strength analysis and wear calculation were completed,which will provide theoretical basis for bucket structure optimization.
