Structural Analysis and Optimization of Mechanical Excavator WK-20 Bucket Based on Discrete Element Method

Abstract:

The structural characteristics and requirements of a bucket, combined with the working experience of an excavator, were analyzed to optimize the structure of a WK-20 bucket. The simulation model was defined by the discrete element method (DEM) to characterize the real interaction between the bucket and different materials. Through an analysis and comparison of the performance of the original and optimized buckets, the latter increased the filling coefficient for different materials. The simulation and optimization based on DEM offered the theoretical basis and a reliable method for the reasonable design of the bucket structure and the entire machine.
