Abstract:

The loss caused by cutting platform vibration and by cuttting cole were the two main form of loss of cole reaping machine whereas reciprocating cutter inertia force was primary factor causing cutting platform vibration. The kinematics and dynamics model of transmission in reciprocating reaping machine were established and the acceleration of primary component were analzed in this paper in order to decrease cutting platform vibration loss. The equations to resolve restraint force in all moving pair were set up thus the expression of inertia force were obtained. The factors of influencing inertia force were put forward based on these analysis. The conclusions were the theoretic foundation to decrese inertia force as well as cutting platform vibration and to optimize mechanism.
