英文摘要：

For further studies on the dynamic characteristics of the conjugate cam seedling-pushing device applied on walking-type rice transplanter, the dynamic model of this device was established. And then, the dynamic analysis was carried out by using the auxiliary analysis software which was compiled based on Visual Basic 6. 0. Finally, the 3-D analysis model was established and its corresponding virtual test was conducted. The result of theoretical calculation coincided very well with that of the simulation test, which proved that the dynamic analysis model was reliable. Besides, it can provide the mathematical model for dynamic optimization and also the basis for subsequent strength calculation and structural design. Compared with the traditional seedling-pushing device, the support position of this new device had smaller force, noise and fluctuation of the force, which can indicate that this novel conjugate cam seedling-pushing device had good dynamic characteristics.
