Calibration and analysis of discrete element simulation parameters of Chinese cabbage seeds.

ABSTRACT:

Objective

To improve the accuracy of parameters used in discrete element simulation test of Chinese cabbage seeds harvesting process.

Methods

Firstly, the key physical parameters of Chinese cabbage seeds were measured. According to the results, the discrete element simulation model was established and the value range of simulation test parameters was determined. Then, the actual repose angle of Chinese cabbage seeds was obtained by physical accumulation test using bottomless conical cylinder lifting method. Plackett-Burman test, steepest climb test, Box-Behnken test and parameter optimization test were carried out in sequence with the actual angle of repose as the response value. Finally, the obtained parameters are verified.

Results

1. The Plackett-Burman test showed
