摘　　要：圆弧齿线圆柱齿轮是一种新型的齿轮传动,能够解决现有渐开线齿轮传动存在的不足。采用有限元方法对不同刀具半径和模数的圆弧齿线圆柱齿轮的动态特性进行研究,以揭示其对其动态特性的影响。在UG中建立了这种齿轮的精确三维模型,并将其导入Workbench分析软件中对这种新型齿轮进行模态分析,仿真结果表明,在其他参数不变的情况下,其各阶固有频率呈降低趋势;刀具半径对其动态特性影响不显著。The circular arc tooth trace(CATT) cylindrical gear is a new type of gear transmission,which can solve the problem existing in the traditional gears. The dynamic characteristics of the CATT gears are studied with different tool radius and modulus based on the finite element method to reveal its influence on its dynamic characteristics. The accurate 3D model of the CATT gear is established in the UG,and it is imported into the Workbench for the modal analysis of this new type of gear. The simulation results show that,in the case of other parameters are the same,the natural frequency of each order is gradually reducing,the influence of the tool radius on its dynamic characteristics is not significant.
