摘　　要：面齿轮的动态啮合力分析是高质量面齿轮传动设计的重要内容。基于面齿轮加工原理和CATIA二次开发方法,得到有限元分析所需的三维几何模型。以接触动力学基本理论为基础,建立合理的有限元分析模型,确定合理的参数,使用ABAQUS软件对面齿轮动态啮合力进行有限元仿真分析与研究,得到面齿轮齿面接触力及齿根弯曲应力在连续啮合过程中的变化规律及转速和负载与面齿轮动态啮合力之间的关联规律。论文工作对高性能面齿轮传动动态性能分析有参考价值。Analysis of the dynamic meshing force of face gear is the important content in the design of face gear drive with high quality.Based on the secondary development of CATIA and the principle of gear machining,the 3Dgeometric modeling of face gear for finite element analysis is obtained.Based on basic theory of contact dynamics,the reasonable finite element analysis model is built and the reasonable parameters are determined.The finite element simulation analysis and study of the dynamic meshing of face gear are carried out by using the ABAQUS,the variation law of the tooth surface contact force and the tooth root bending stress of face gear in the process of continuous mesh and the association law of the among the speed,load and tooth surface dynamic meshing are obtained.It will be provide some reference value for dynamic performance analysis of high-performance face gear drive.
