摘要
在三维空间建立了拖拉机犁耕机组的线性１０自由度力学数学模型，以实测信号为依据，建立机组的激励谱矩阵，探讨了在同时受车轮位移激励和犁的外力激励时机组动态响应的计算方法，分析了犁耕机组的振动特点。
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.
