| Abstract: | In the paper,the liner 10-DOF model of the tractor-plow unit in three dimension space isformulated.According to the experimental data. the corresponding input PSD matrix is estab-lished.When two kinds of inputs are acting,the response is studied with two methods. Alsothe vibration characteristics are researched. |
