Simulation Study on Different Bucket Wide in Shoveling Loading Process Based on EDEM

Abstract

The study is based on the bucket wide in shovel loading process, to know about mechanism about different bucket wide in shovel loading process through the motion regularity of the material. Then simulation experiment was applied by a shovel-loader for different bucket wide in the discrete software EDEM. The results show that the new windrow frontier is loose when inserting material. As a result of the bucket disturbance, slope material is moved downward. The impact area is greater as material bucket width is larger. With the increase of bucket insert depth, bucket goes forward extrusion materials, material goes toward small loose zone and stress area. During the process of inserting, material is squeezed into a dense zone and then solid zone is in damaged state. The smaller bucket width is, the smaller the impact is on the material, vice versa. In the phase of ascension, the bucket shear extrusion windrow, shearing effect is obvious. The affection of the shearing area of the particles becomes greater because of the increase of bucket width. The more obstacles the shovel can overcome, with the rotation of the bucket to ascend, area is decreased about interacting with bucket, material goes toward the loose area and tends to stability.
