摘　　要：为避免高速轴齿轮结构在高速运转过程中出现共振破坏,以高速轴齿轮结构为研究对象,利用三维建模软件建立了高速轴齿轮结构的三维模型;再导入ANSYS Workbench中,对高速轴齿轮结构进行静力学及模态分析。高速轴齿轮结构的静应力分析结果表明:齿轮在静应力工况下最大应力值为65 MPa,最大变形量为0.0138mm,同时通过结合静应力的约束条件,分析了有预应力的模态,得到了高速轴齿轮结构的前六阶固有频率及动态特性,其固有频率范围是1159.7～1785.5Hz,为高速轴齿轮结构的设计和改进提供参考。In order to avoid the resonance failure of high-speed shaft gear structure in high-speed operation,the high-speed shaft gear structure is taken as the research subject, the 3D model of high speed axle gear structure is established by 3D modeling software, and then the statics and modal analysis of the high-speed axle gear structure is introduced into ANSYS Workbench . The static stress analysis of the high speed shaft gear structure shows that the maximum stress value of the gear in the static stress condition is 65 M Paand the maximum deformation amountis 0.0138 mm . At the same time, the prestress mode is analyzed bycom bining the static stress constraint conditions. The first six order natural frequencies and dynamic characteristics of the high speed shaft gear structure are obtained, and the inherent frequency of the high speed axle gear structure is also acquired. The rate range is from 1159.7 to 1785.5 Hz , whichmay provide reference for the design and improvement of high-speed shaft gear structure.
