摘　　要：使用ANSYS的未激励齿轮的齿廓、周期变化、APDL语言建立了齿轮系统的虚线网格的参数模态分析模型。采用APDL线性点网格分析表定义了一个特殊的界面,输入参数并自动读取,调用分析仪并执行动态差计算。通过分析固有频率与阶数之间关系来反映点线啮合齿轮动力学模态变化过程,以及通过压力角与阶数之间关系折射出对模态的影响过程。此分析程序的开发对点线啮合齿轮拟态的分析和设计能力奠定了强有力的基础。This article uses ANSYS's tooth profile and period changes of unexcited gears,and uses APDL language to establish a parametric modal analysis model of the dashed grid of the gear system.The APDL linear point grid analysis table is used to define a special interface,input parameters and automatically read,call the analyzer and perform dynamic difference calculation.By analyzing the relationship between the natural frequency and the order,the dynamic mode change process of the point-line meshing gear is reflected,as well as the influence process of the refraction between the pressure angle and the order on the mode.The development of this analysis program lays a strong foundation for the analysis and design ability of point line meshing gear mimicry.
