| Abstract: | To enhance accuracy and velocity of agricultural materials weighing, the dynamic characteristics of a hybrid quantifying-weighing system was analyzed, the mathematical model of the weighing system was established, the factors influencing the dynamic characteristics of the weighing system was investigated, and the methods to improve the dynamic characteristics was suggested. The experimental data show that the means of adding damper and adopting digital compensation can enhance and improve the dynamic characteristics of the weighing system. |
