摘　　要：针对高速齿轮传动系统工作过程中的冲击振动问题,以某齿轮传动系统中三根高速轴上的齿轮为研究对象,利用ANSA有限元前处理软件建立带轴承的多级平行轴齿轮传动系统模型。采用瞬态动力学仿真分析与模态分析相结合的手段,研究了弧齿锥齿轮以及渐开线直齿轮在复杂轮系中的非线性动力学特性。结果表明:在高速齿轮传动系统中,轴的弹性、轴承游隙以及来自其他齿轮副的动态激励会导致齿轮副发生偏载、啮合力增大、啮合稳定性变差以及低频共振等异常现象。Aiming at the impact vibration of the high-speed gear transmission system in the working process,with the gear on the three high-speed shafts in a gear transmission system as the research object,this paper establishes a multi-stage parallel shaft gear transmission system model with bearings by ANSA finite element pre-processing software.The nonlinear dynamic characteristics of spiral bevel gears and involute spur gears in the complex gear train system are studied through transient dynamic simulation and modal analysis.The results show that,in the high-speed gear transmission system,elastic deformation of the shaft,bearing clearance and dynamic excitation from other gear pairs will lead to abnormal phenomena such as unbalanced load,an increase of meshing force,deterioration of meshing stability and low-frequency resonance of the gear pairs.
