分析了国内林木采种的现状和特点，提出了一种适用于我国东北林区红松采种作业的振动采种机，对总体结构进行了设计，并用Pro/E4．0软件进行了三维实体造型。该机的主要特点是能自动修剪障碍树枝、采种效率高、体积小、作业时对母树的破坏小。最后，运用ANSYS有限元分析软件对振动采种机的机架进行了自由模态分析，对各阶模态进行研究并与振动采种机的工作频率进行比较，得出了机架振动的理论参数，从而有效地防止了出现机架固有频率与工作频率相近的共振破坏现象。

The paper analyzed the characteristics of the Seed harvester and put forward a new vibrating seed harvester which is suitable for korean pine in northeast China garden .It also designed its general structure and finished its solid modeling by the use of Pro/E4 .0 .Its main characteristics are trim obstacles branches automatically , small volume , seed production efficiency and small damage on mother trees when working .Analyze the Free modal of the vibration seed pro-duction frame use ANSYS Workbench .Compared with the operating frequency of the vibration seed production machine to prevent the emergence of the phenomenon that natural frequency of the frame similar operating frequency cause reso -nance destruction .
