Optimizing threshing system of a combine harvester using the Discrete Element Method

Zoomlion Heavy Industry have been developing a simulation model of a threshing system of a combine harvester using the Discrete Element Method (DEM). Optimization of the performance parameters like grain recovery, grain damage and grain loss with an optimal use of power is the overall goal of the model. Dealing with small size multi-spheres with varying material properties and processing of large number of particles in a reasonable time were the real challenges which we successfully handled using Altair’s EDEM software. An important performance indicator of the agricultural crop processing and grain handling systems is the damage to the grain that occurs in the system.

Zoomlion are continuously discussing and working with Altair’s team to make it possible to study this important performance parameter. They are fully determined to address & solve the problems which are considered un-solvable in construction and agricultural industry of the world.
