The simulation analysis of different tooth numbers of loader bucket based on EDEM

Abstract

To study the loader from the aspects of bucket tooth numbers in the process of shoveling. Firstly, to simplify the three-dimensional geometric modeling in “four basic parameters method”, Then simulation experiment is applied by a shovel-loader for different teeth in the discrete software EDEM, the influence of the number of bucket teeth is analyzed by using the single factor analysis method about resistance of the shovel. To determine whether the number of teeth is significant. Research results show that the resistance of the shovel gradually increases and renders the index distribution when the shovel is in the insertion phase, it has an influence on shovel loading about the numbers. The number of bucket tooth almost has no effect on shoveling loading resistance in lifting stage. According to the whole process, considering the factor of full bucket rate and the resistance of the shovel, five bucket tooth uneven distribution model will be the right choice.
