%X 本文以板栗去皮机为例，利用SolidWorks对板栗去皮机进行三维建模并简化处理，然后导入Ansys Workbench软件，对板栗去皮机中重要部件：机架和螺旋送料机，进行静力学分析和模态分析，求解出机架和螺旋送料机的最大应力、变形量、固有频率和振型，结果表明：机架最大应力为：15.321 MPa，最大变形量为：1.7452 mm，前六阶固有频率范围：12.926~61.197 Hz；螺旋送料机最大应力为：1.7489 MPa，最大变形量：9.0035 mm，前六阶固有频率：39.525~131.77 Hz。机架和螺旋送料机最大应力均小于材料的屈服强度，机架由于质量大，前六阶固有频率均在100 Hz以内，并未发现机架和螺旋送料机存在共振频率。<br />
In this paper, the chestnut peeling machine is taken as an example. The three-dimensional model-ing and simplification of the chestnut peeling machine are carried out by SolidWorks, and then im-ported into Ansys Workbench software. The static analysis and modal analysis of the important parts of the chestnut peeling machine: frame and screw feeder are carried out. The maximum stress, deformation, natural frequency and vibration mode of the frame and screw feeder are solved. The results show that the maximum stress of the frame is 15.321 MPa, the maximum deformation is 1.7452 mm, and the first six natural frequencies range: 12.926~61.197 Hz; the maximum stress of the screw feeder is 1.7489 MPa, the maximum deformation is 9.0035 mm, and the first six natural frequencies are 39.525~131.77 Hz. The maximum stress of the frame and the screw feeder is less than the yield strength of the material. Due to the large mass of the frame, the first six natural fre-quencies are all within 100 Hz, and the resonance frequency of the frame and the screw feeder is not found.
