Tracing of the rapeseed movement by using the contrast point tracking method for DEM model verification

Original language description

For designing the efficient storage and transport of rapeseed, it is necessary to follow the rules of bulk material, know its properties, and use appropriate equipment. The mentioned properties of bulk material are essential for simulating the numerical model and obtaining the parameters of the geometry particle tracing during the rapeseed manipulation. In order to determine the angle of repose and mechanical properties of rapeseed, the results of previous experiments were used. The aim of this paper was to propose the methodology for calculating the traces of individual particles using the contrast point method during a real test to calibrate and verify a numerical model of the same system as in a real test. RockyDEM software was used to create the numerical model of rapeseed. The numerical model was used to test the flow analysis of rapeseed particles. The experiment measuring rapeseed particle traces was performed using an assembled experimental device. The rapeseed particles and the contrast point particles were poured out from the device, and a camera recorded the process. In parallel with the real experiment, the angle of repose test was performed on the same device to verify the numerical model. The results showed that the methodology is suitable for the DEM model verification with an accuracy of 3,77 mm in the X axis, 0,55 mm in the Y axis and 1,7 mm in the Z axis. This confirmed that the proposed method is suitable for determining the surface behaviour of bulk material to verify the DEM model.
