Abstract
As a result of numerical simulation of the seed retarder of the John Deere pneumatic seed drill in the software package Star CCM + visualization of the process of seed movement and air flow in the working area of the retarder was obtained. According to the results of numerical modeling and processing of data obtained in the software package Wolfram Mathematica obtained third-order regression equations in decoded form without significant coefficients according to Student's t-test dependences of air flow rate Vaout, seed speed Vpout the velocity of the air flow at the inlet Vain and the ratio of the area of the outlets to the area of the inlet ε. As a result of solving the compromise method of scalar ranking by minimizing the multiplicative function taking into account the coefficient of importance of the private criterion at fixed values of air flow velocity at the inlet Vain in the range from 5 m/s to 25 m/s seed. It is established that at the specified range of air flow rate at the inlet Vain it is necessary to adjust the seeding rate by the coefficient η, which is in honey from 1.47 to 2.56.
