DESIGN OF SIMULATION STRATEGY FOR CORN CLEANING ON DISCRETE ELEMENT METHOD

摘要

The past efforts made on the corn cleaning dynamics were reviewed. Based on Discrete Element Method model, a simulation method for corn cleaning dynamics was then proposed, composing the following design factors: 1. 2-D discrete model and its related factors; 2. parities and magnitude of computation, consideration of the two factors upon application; 3. test platform design. The implementation of this plan will illustrate the dynamics of corn cleaning, benefiting the efficiency of cleaning machine design and the improvement of production economies.
