摘　　要：根据齿轮啮合原理,准确求解出复杂的齿廓曲线;采用MATLAB-APDL混合建模方法,创建精确的齿轮有限元模型,对齿轮传动线外啮合冲击问题进行了研究,推导出齿轮啮合冲击碰撞数学模型,通过实例计算,求出了冲击速度与冲击力、齿宽与冲击力的数量关系,获得了比较精确的冲击时间.线外啮合冲击的深入研究,对改善齿轮传动性能和提高齿轮设计制造水平具有一定的意义.Based on the gear engagement principles, the exact curve of tooth profile is produced. With composite modeling via MATLABTM and APDLTM, a precise FEM gear model is established. Upon completion of the mathematical model for gear meshing impact and collision, the corner contact impact process is simulated to quantitatively obtain the relationships between impact velocity and force, as well as between gear breadth and impact force. Therein, the accurate impact timing can improve the performance of gear transmission and upgrade the gear design and manufacturing level.
