摘　　要：以某混动车型的齿轮传动系统为研究对象,采用集中参数法建立了传动系统动力学模型。在各个齿轮副的偏心误差、齿频误差、时变啮合刚度的共同作用下,用数值方法求解了传动齿轮在轻负荷低速巡航与高速超车两种工况下的动态特性。将传动系统与箱体耦合,建立齿轮箱有限元模型,加载齿轮动态啮合力,利用Ansys软件仿真得到了两种工况切换过程中箱体的振动特性。通过搭建台架试验,对比验证了动力学模型及仿真计算的正确性。通过测试得到出现最大振幅的箱体位置,对优化传动系统结构、改善齿轮箱的振动特性提供了有力依据。Taking the gear transmission system of a hybrid vehicle as the research object,the lumped parameter method is used to establish the dynamic model of the transmission system.Under the combined action of the eccentricity error,tooth frequency error,and time-varying meshing stiffness of each gear pair,the numerical method is used to solve the dynamic characteristics of the transmission gear under light-load,low-speed cruising and high-speed overtaking.The transmission system is coupled with the box body,the finite element model of the gear box is established,the dynamic meshing force of the gear is loaded,and the vibration characteristics of the box body during the switching process of the two working conditions are simulated using the Ansys software.A bench test for comparing and verifying the correctness of the dynamic model and simulation calculation is set up.The position of the box with the largest amplitude through the test is obtained,which provides a strong basis for optimizing the structure of the transmission system and improving the vibration characteristics of the gear box.
