摘　　要：用有限元方法,建立汽车变速箱齿轮结构的三维动力学模型。模拟齿轮实际啮合过程中的连续冲击载荷,研究不同转速下齿轮齿根应力历程,得到随着转速变化,齿根应力的变化规律,对于齿轮强度及弯曲疲劳寿命计算具有一定的指导意义。Three-dimensional dynamics model of transmission gear was built by means of finite element method. Continuous impulsive load in gear meshing process was simulated in order to research gear root stress load course characteristics under varying rotate speed, which is benefit to calculate stress and bending fatigue of gear.
